98-361.examcollection.premium.exam.276q Number: 98-361 Passing Score: 800 Time Limit: 120 min File Version: 18.0

Exam code: 98-361 Exam name: Software Development Fundamentals Version 18.0

Question Set 1 QUESTION 1 You are creating an application for computers that run Windows XP or later. This application must run after the computer starts. The user must not be aware that the application is running. The application performs tasks that require permissions that the logged-in user does not have. Which type of application allows this behavior? A. B. C. D.

Windows Service application Windows Forms application DOS batch file Terminate-and-stay-resident (TSR) program

Correct Answer: A Section: [none] Explanation Explanation/Reference: QUESTION 2 An application presents the user with a graphical interface. The interface includes buttons that the user clicks to perform tasks. Each time the user clicks a button, a method is called that corresponds to that button. Which term is used to describe this programming model? A. B. C. D.

Functional Service oriented Structured Event driven

Correct Answer: D Section: [none] Explanation Explanation/Reference: QUESTION 3 How does a console-based application differ from a Windows Forms application? A. B. C. D.

Console-based applications require the XNA Framework to run. Windows Forms applications do not provide a method for user input. Windows Forms applications can access network resources. Console-based applications do not display a graphical interface.

Correct Answer: D Section: [none] Explanation Explanation/Reference: QUESTION 4 Which type of Windows application presents a parent window that contains child windows? A. Application programming interface (API)

B. Single-document interface (SDI) C. Multiple-document interface (MDI) D. Command-line interface (CLI) Correct Answer: C Section: [none] Explanation Explanation/Reference: A multiple document interface (MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single document interfaces (SDI) where all windows are independent of each other. QUESTION 5 The purpose of a constructor in a class is to: A. B. C. D.

Initialize an object of that class. Release the resources that the class holds. Create a value type. Inherit from the base class.

Correct Answer: A Section: [none] Explanation Explanation/Reference: Each value type has an implicit default constructor that initializes the default value of that type. QUESTION 6 A class named Manager is derived from a parent class named Employee. The Manager class includes characteristics that are unique to managers. Which term is used to describe this object-oriented concept? A. B. C. D.

Encapsulation Data modeling Inheritance Data hiding

Correct Answer: C Section: [none] Explanation Explanation/Reference: Classes (but not structs) support the concept of inheritance. A class that derives from another class (the base class) automatically contains all the public, protected, and internal members of the base class except its constructors and destructors. Incorrect: not A: Encapsulation is sometimes referred to as the first pillar or principle of object-oriented programming. According to the principle of encapsulation, a class or struct can specify how accessible each of its members is to code outside of the class or struct. Methods and variables that are not intended to be used from outside of the class or assembly can be hidden to limit the potential for coding errors or malicious exploits. QUESTION 7 Which term is used to describe a class that inherits functionality from an existing class? A. Base class B. Inherited class C. Derived class

D. Superclass Correct Answer: C Section: [none] Explanation Explanation/Reference: Classes (but not structs) support the concept of inheritance. A class that derives from another class (the base class) automatically contains all the public, protected, and internal members of the base class except its constructors and destructors. QUESTION 8 Two classes named Circle and Square inherit from the Shape class. Circle and Square both inherit Area from the Shape class, but each computes Area differently. Which term is used to describe this object-oriented concept? A. B. C. D.

polymorphism encapsulation superclassing overloading

Correct Answer: A Section: [none] Explanation Explanation/Reference: You can use polymorphism to in two basic steps: Create a class hierarchy in which each specific shape class derives from a common base class. Use a virtual method to invoke the appropriate method on any derived class through a single call to the base class method. QUESTION 9 You create an object of type ANumber. The class is defined as follows.

What is the value of _number after the code is executed? A. B. C. D.

Null 0 3 7

Correct Answer: C Section: [none] Explanation Explanation/Reference: QUESTION 10 You need to allow a consumer of a class to modify a private data member. What should you do? A. B. C. D.

Assign a value directly to the data member. Provide a private function that assigns a value to the data member. Provide a public function that assigns a value to the data member. Create global variables in the class.

Correct Answer: C Section: [none] Explanation Explanation/Reference: In this example (see below), the Employee class contains two private data members, name and salary. As private members, they cannot be accessed except by member methods. Public methods named GetName and Salary are added to allow controlled access to the private members. The name member is accessed by way of a public method, and the salary member is accessed by way of a public read-only property. Note: The private keyword is a member access modifier. Private access is the least permissive access level. Private members are accessible only within the body of the class or the struct in which they are declared Example: class Employee2 { private string name = "FirstName, LastName"; private double salary = 100.0; public string GetName() { return name; } public double Salary { get { return salary; } } } QUESTION 11 You are designing a class for an application. You need to restrict the availability of the member variable accessCount to the base class and to any classes that are derived from the base class. Which access modifier should you use? A. B. C. D.

Which term is used to describe this object-oriented concept? A. B. C. D.

multiple inheritance polymorphism data hiding encapsulation

Correct Answer: A Section: [none] Explanation Explanation/Reference: Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects: * At run time, objects of a derived class may be treated as objects of a base class in places such as method parameters and collections or arrays. When this occurs, the object's declared type is no longer identical to its run-time type. * Base classes may define and implement virtual methods, and derived classes can override them, which means they provide their own definition and implementation. At run-time, when client code calls the method, the CLR looks up the run-time type of the object, and invokes that override of the virtual method. Thus in your source code you can call a method on a base class, and cause a derived class's version of the method to be executed. QUESTION 108 This question requires that you evaluate the underlined text to determine if it is correct. A data dictionary that describes the structure of a database is called metadata.

QUESTION 112 Which three items are benefits of encapsulation? (Choose three.) A. B. C. D. E.

maintainability flexibility restricted access inheritance performance

Correct Answer: ABC Section: [none] Explanation Explanation/Reference: Encapsulation is the packing of data and functions into a single component. In programming languages, encapsulation is used to refer to one of two related but distinct notions, and sometimes to the combination thereof: * A language mechanism for restricting access to some of the object's components. * A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data. Incorrect: not D: Encapsulation is one of the four fundamental OOP concepts. The other three are inheritance, polymorphism, and abstraction. QUESTION 113 This question requires that you evaluate the underlined text to determine if it is correct. When a base class declares a method as virtual, the method is hidden from implementation bv a derived class. Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct. A. B. C. D.

No change is needed can be overridden with its own implementation by a derived class must be overridden in any non-abstract class that directly inherits from that class cannot be overridden with its own implementation by a derived class

Correct Answer: B

Section: [none] Explanation Explanation/Reference: The implementation of a non-virtual method is invariant: The implementation is the same whether the method is invoked on an instance of the class in which it is declared or an instance of a derived class. In contrast, the implementation of a virtual method can be superseded by derived classes. The process of superseding the implementation of an inherited virtual method is known as overriding that method. QUESTION 114 This question requires that you evaluate the underlined text to determine if it is correct.

No change is needed serialization decoding encoding

Correct Answer: B Section: [none] Explanation Explanation/Reference: Serialization is the process of converting an object into a stream of bytes in order to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. Serialization allows the developer to save the state of an object and recreate it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications. QUESTION 115 You have a Microsoft ASP.NET web application. You need to store a value that can be shared across users on the server. Which type of state management should you use? A. B. C. D.

Session ViewState Application Cookies

Correct Answer: C Section: [none] Explanation Explanation/Reference: Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and sessions. Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another. Incorrect:

not A: Session State contains information that is pertaining to a specific session (by a particular client/ browser/machine) with the server. It's a way to track what the user is doing on the site.. across multiple pages...amid the statelessness of the Web. e.g. the contents of a particular user's shopping cart is session data. Cookies can be used for session state. Not B: Viewstate is a state management technique in asp.net. ASP.NET Viewstate is preserving the data between the requests or postbacks and stored in hidden fields on the page. QUESTION 116 This question requires that you evaluate the underlined text to determine if it is correct. The Response.Redirect method is used to transfer processing of the current page to a new page, and then return processing back to the calling page once processing of the new page has completed. Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct. A. B. C. D.

No change is needed Server.Transfer method Server.Execute method meta http-equiv="refresh" tag

Correct Answer: C Section: [none] Explanation Explanation/Reference: The Execute method calls an .asp file, and processes it as if it were part of the calling ASP script. The Execute method is similar to a procedure call in many programming languages. Incorrect: * Response.Redirect Method The Redirect method causes the browser to redirect the client to a different URL. * The Server.Transfer method sends all of the information that has been assembled for processing by one .asp file to a second .asp file. QUESTION 117 You are creating an application for a priority help desk center. The most recent call must be handled first. Which data structure should you use? A. B. C. D.

queue hashtable stack binary tree

Correct Answer: C Section: [none] Explanation Explanation/Reference: In computer science, a stack is a particular kind of abstract data type or collection in which the principal (or only) operations on the collection are the addition of an entity to the collection, known as push and removal of an entity, known as pop. The relation between the push and pop operations is such that the stack is a Last-In-First-Out (LIFO) data structure. In a LIFO data structure, the last element added to the structure must be the first one to be removed. QUESTION 118 You plan to create an application for your company. The application will run automated routines and write the results to a text-based log file. Little or no user interaction is required. Security requirements on the host computers prevent you from running applications on startup, and users

must be able to see the status easily on the screen. The host computers also have limited memory and monitors that display only two colors. These computers will have no network connectivity. Which type of application should you use for this environment? A. B. C. D.

multiple inheritance encapsulation polymorphism data hiding

Correct Answer: C Section: [none] Explanation Explanation/Reference: Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects: * At run time, objects of a derived class may be treated as objects of a base class in places such as method parameters and collections or arrays. When this occurs, the object's declared type is no longer identical to its run-time type. * Base classes may define and implement virtual methods, and derived classes can override them, which means they provide their own definition and implementation. At run-time, when client code calls the method, the CLR looks up the run-time type of the object, and invokes that override of the virtual method. Thus in your source code you can call a method on a base class, and cause a derived class's version of the method

to be executed. QUESTION 108 This question requires that you evaluate the underlined text to determine if it is correct. Converting a value type to a reference type in an object is called boxing.

in the Web.config file in the server-side code only in the client-side code only in both the client-side code and the server-side code

Correct Answer: D Section: [none] Explanation Explanation/Reference: From version 2.0 on, ASP.NET recognized the JavaScript capabilities of these browsers, so client-side validation is now available to all modern browsers, including Opera, Firefox, and others. Support is even better now in ASP.NET 4.0. That said, it's important not to forget that JavaScript can be disabled in any browser, so client-side validation cannot be relied upon--we must always validate any submitted data on the

server. QUESTION 111 You plan to create an application for your company. The application will run automated routines and write the results to a text-based log file. Little or no user interaction is required. Security requirements on the host computers prevent you from running applications on startup, and users must be able to see the status easily on the screen.

QUESTION 112 Which three items are benefits of encapsulation? (Choose three.) A. B. C. D. E.

restricted access flexibility maintainability performance inheritance

Correct Answer: ABC Section: [none] Explanation Explanation/Reference: Encapsulation is the packing of data and functions into a single component. In programming languages, encapsulation is used to refer to one of two related but distinct notions, and sometimes to the combination thereof: * A language mechanism for restricting access to some of the object's components. * A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data. Incorrect: not E: Encapsulation is one of the four fundamental OOP concepts. The other three are inheritance, polymorphism, and abstraction. QUESTION 113 This question requires that you evaluate the underlined text to determine if it is correct.

The Execute method is similar to a procedure call in many programming languages. Incorrect: * Response.Redirect Method The Redirect method causes the browser to redirect the client to a different URL. * The Server.Transfer method sends all of the information that has been assembled for processing by one .asp file to a second .asp file. QUESTION 115 You have a Microsoft ASP.NET web application. You need to store a value that can be shared across users on the server. Which type of state management should you use? A. B. C. D.

session application cookies ViewState

Correct Answer: B Section: [none] Explanation Explanation/Reference: Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and sessions.

Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another. Incorrect: not A: Session State contains information that is pertaining to a specific session (by a particular client/ browser/machine) with the server. It's a way to track what the user is doing on the site.. across multiple pages...amid the statelessness of the Web. e.g. the contents of a particular user's shopping cart is session data. Cookies can be used for session state. Not D: Viewstate is a state management technique in asp.net. ASP.NET Viewstate is preserving the data between the requests or postbacks and stored in hidden fields on the page. QUESTION 116 This question requires that you evaluate the underlined text to determine if it is correct. The process of transforming compiled C# code into an XML string for a web service is known as deserialization. Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed" if the underlined text makes the statement correct. A. B. C. D.

No change is needed serialization decoding encoding

Correct Answer: B Section: [none] Explanation Explanation/Reference: Serialization is the process of converting an object into a stream of bytes in order to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. Serialization allows the developer to save the state of an object and recreate it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications. QUESTION 117 This question requires that you evaluate the underlined text to determine if it is correct. A data dictionary that describes the structure of a database is called metadata. Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct. A. B. C. D.

Understand computer storage and data types SCENARIO: Ken is a soccer coach who has a difficult time keeping track of all of his players: At the beginning of

the season, each of his players filled out a paper with personal data, but it always takes him a long time to find the information he needs.

Cassie is one of his brightest players, and Ken knows that she’s a computer programmer. Tired of shuffling through the huge stack of papers, he asks her to create a program to keep track of his records. The program will need to store each player’s full name, jersey number, age, gender, height and weight, as well as goals scored and number of games played. Cassie agrees to develop the software for him, but she has some decisions to make . . .

1. Which of the following data types would be the best choice for keeping track of players’ ages and jersey numbers using the least amount of memory? a. short b. byte c. int

2. As with any program, some data will be stored on the heap, while other

data is placed on the stack. Which of the following will be stored on the heap? a. player’s name b. height c. age

Remember: String is a reference data type.

3. It would make sense to store one of these variables as a char. Which one? a. player’s name b. weight c. gender

Understand computer storage and data types

5

Answers 1. A good choice for keeping track of jersey numbers and ages is: b. byte. It uses the least amount of memory, but still holds numbers up to 255—more than enough for ages or jersey numbers!

2. Player data that will be stored on the heap includes: a. player’s name. This will be stored as a String.

3. The variable that could be stored as a char is: c. gender. ‘M’ for males, ‘F’ for females!

Essential details • Integral data types, such as byte, integer, short, and long store whole numbers—such as the number of goals a player has scored. • Floating point data types, like float, single, and double can represent numbers that include fractional data, such as a player’s height. • Value data types go on the stack; reference data types go on the heap. Look at the first vowel in each to help you remember: Value = stack. Reference = heap. FAST TR ACK HELP

OBJECTIVE


Understand computer decision structures SCENARIO: Reina has created a simple DVR application to record her favorite television programs, but her code has some bugs. She’s a big sports fan and always wants to record the broadcasts of sporting events, even if they conflict with another of her favorite programs.

For non-sport favorites, she does not want to record reruns; however, if the scheduled time of a favorite program conflicts with another favorite and will be broadcast again later, she wants to wait and record it in the future. Unfortunately, her program is not working correctly. Many television programs that she doesn’t want are being recorded; the programs she DOES want are only being recorded if they are broadcast later. The C# code (with line numbers added) of Reina’s DVR program looks like this: 1: if (isSportsEvent) { 2: 3:

RecordShowNow(); }

4: else { 5:

if (!isConflict || !isRerun) {

6:

RecordShowNow();

7:

}

8:

if (isConflict && isOnLater); {

9: 10:

RecordShowLater(); }

11: }

1. Which line is causing shows to be recorded now even if there is a conflict?

2. How should line 8 be rewritten? a. if (isOnLater); { b. if (isConflict || isOnLater); { c. if (isConflict && isOnLater) {

3. Reina has placed two

control structures (lines 5–7 and lines 8–10) inside her first control structure. This technique is known as: a. parenting b. encapsulating c. nesting

Indentation used in the code is good programming style, but it has no effect on the execution of the statement.

a. line 4 b. line 5 c. line 8 Understand computer decision structures

7

Answers 1. Shows are being recorded now even if there is a conflict because: b. Line 5. The conditional-OR ( || ) returns true if the show isn’t a rerun, even if isConflict is true.

2. Line 8 should read: c. if (isConflict && isOnLater) { The semicolon at the end of the line terminates the conditional—RecordShowLater() will always be called.

3. Placing control structures inside other control structures is called: c. nesting

Essential details • The code in the parentheses of an if-statement must be a complete Boolean (“conditional”) expression. Example: • “If a person is at least 18 years old, that person will vote” if (age > 18) vote(); • Logical operators allow programmers to join two expressions. Examples: • “I will stay home if it’s raining OR if it’s snowing.” (logical-OR) if (isRaining | isSnowing) stayHome(); If EITHER is true, the entire expression is true; stayHome is called. • We will buy a new computer if the current one is more than three years old AND computers are on sale. (logical-AND) if (computerAge > 3 & isOnSale) buyComputer(); If BOTH are true, the entire expression is true; buyComputer is called. FAST TR ACK HELP

Identify the appropriate method for handling repetition SCENARIO: Adriana is creating a point-of-sale (cash register) application for Fourth Coffee. Her responsibility is to create a password-protected login system to ensure security of the system. She has finished the login window and password check, but she is having trouble implementing it correctly.

Adriana’s project manager wants the system to give the user three attempts to login correctly before locking the system. In Adriana’s most recent version, the system prompts the user for a name and password three times— even if the user correctly logs in on the first try. After the third attempt, the system always locks—even if the input is correct.

1. Adriana is using a for loop, which works best when: a. the number of iterations is known and is unlikely to change during execution b. the number of iterations is known but is likely to change during execution c. the number of iterations is unknown

2. What control structure would be best for Adriana’s login system? a. for loop b. while loop c. a recursive method

3. How many times does a do..while loop execute? a. at least zero times b. at least one time c. at least two times

An “iteration,“ in this context, is one trip through the loop.

Identif y the appropriate method for handling repetition

9

Answers 1. for loops work best when: a. the number of iterations is known and is unlikely to change

2. The best control structure for this situation is: b. while loop. The number of times the loop will need to be executed is uncertain: It depends on the data entered by the user. In this case, a while loop (or do..while) is usually the best choice.

3. How many times does a do..while loop execute? b. at least one time. Unlike a do..while loop, a while loop may not execute at all!

Essential details • The for loop executes a statement, or a block of statements, based on the value of a control variable (also called a counter). Example: for (int i = 0; i < 10; i++) Console.WriteLine(i);

Note: i (the control variable) is initialized to zero. The loop will continue as long as i is less than 10. After each iteration, i is incremented. • The while loop executes a statement or block of statements repetitively based on a Boolean expression. You can think of it as a repeating if statement. Example: int i = 0; while (i < 10) { Console.WriteLine(i);

Note: This loop is essentially identical to the for loop example. The Boolean expression is checked before the loop executes, so it may never run at all. For instance, if i was initialized to 20, the expression would evaluate to false and the loop would not execute. • The do..while loop is similar to a while loop, but the Boolean expression is not checked until after the code executes. Example: int i = 0; do { Console.WriteLine(i); ne(i); ; i++;} while (i < 10); 0);

Note: Even if i is initialized ized to 20 (instead of 0), the e loop will execute one time me before the Boolean expression is evaluated..

OBJECTIVE


Understand error handling SCENARIO: Lionel is a student at the School of Fine Art. To help pay his tuition, he took a job in the school’s student records department. He developed a program that calculates each student’s grade point average (GPA). He thought it would be simple, because he knows that the formula is:

total grade points divided by total credit hours attempted However, Lionel’s program crashes with new students who have not attempted any credit hours, instead of just giving them a GPA of 0.0. Here is his code in C# (line numbers added): 1: double GPA; 2: GPA = totalGP / creditHoursAttempted; 3: Console.WriteLine(GPA);

1. Given what we know about the problem, what is the most likely exception this code will throw? a. DivideByZeroException b. NullReferenceException c. StackOverflowException

2. What structure should Lionel use to handle the exception? a. do-catch b. catch-exception c. try-catch

3. Which of the following should Lionel’s catch-block probably include? a. creditHoursAttempted = 1.0; b. totalGP = 4.0; c. GPA = 0.0;

An exception is an error that cannot be detected by the compiler but occurs when the program is executed. It is referred to as a “runtime error.”

Understand error handling

11

Answers 1. The exception most likely creating the problem is:

a. DivideByZeroException. If a student’s creditHoursAttempted is zero,

an exception will occur.

2. The structure that will handle the exception is: c. try-catch

3. Lionel’s catch-block should probably include: c. GPA = 0.0;. Because the division has already been attempted, there’s no reason to change the values used in the calculation.

Essential details • An exception is an object that contains information about an error. • Developers use the terms throw and catch when talking about exceptions. When an exception occurs it is thrown. Therefore, you should catch any exceptions your program may encounter. • Think of a try statement as a warning to the computer that you’re about to try something that may not work. “I’m going to do some division, and it might result in a DivideByZeroException!” • The catch block executes if the exception does occur. You can leave this block empty but generally it’s good to put your “backup plan” in the catch block. In Lionel’s case, that means setting the GPA to 0.0. If no exception is thrown, the catch block is skipped. d. • A try-catch structure doesn’t prevent the exception from being thrown, it simply gives i the developer a chance to keep the program from crashing.

Understand the fundamentals of classes Tailspin Toys is developing a simple, robotic dog for small children. The dog will connect to a computer via a USB cable, and kids will be able to use a simple application to personalize the toy to their liking. Although the hardware is nearly complete, Tailspin has not yet created the software that owners will use to customize their toy dog. Viktor has been hired to begin work on the software. SCENARIO:

Initially, Viktor will need to design a class to represent the dogs. Naturally, the class will be named Dog. The toy—and therefore the Dog class—will need to keep track of the dog’s name, age, and gender, and it will be able to bark, walk, wag its tail, and sit. So far, he has written the following C# code public class Dog { public Dog() { name = “Hugo”; age = 1; gender = ‘M’; } }

1. Which of the following would

Many classes have more than one constructor.

be a property in the Dog class? a. bark

b. name c. Dog()

2. To create a Dog with a different

name, age, or gender, Viktor should add: a. another constructor

b. more properties c. a creation event

3. Which line of code correctly

creates a new Dog in C#? a. Dog hugo = Dog.new(); b. Dog hugo = new Dog(); c. new Dog hugo = Dog(); Understand the fundamentals of classes

15

Answers 1. Which member is a property? b. name

2. To create a different Dog, Viktor should add: a. another constructor

3. Which C# code creates a Dog? b. Dog hugo = new Dog();

Essential details • An object often represents something from the real world; in this case, the Dog class represents the robotic toy (or, it simply represents a dog). • In object-oriented design, verbs (such as barking, walking, tail-wagging, and sitting) are typically methods; attributes (such as name, age, and gender) are properties or fields. • A field is a variable declared within a class; a property provides a simple way to access the data stored in a field. • A class is like a blueprint. It defines the properties and methods that all objects of that class will have in the same way a blueprint defines the attributes of a house. • Multiple objects can be created from a class, or instantiated. Similarly, many houses can be built from one blueprint. • Objects are instantiated (created) with the new keyword.

OBJECTIVE


Understand inheritance SCENARIO: As Tailspin Toys continues to develop its robotic dog toy, early marketing tests reveal that customers would like to choose from different breeds of robotic dogs. As a result, Tailspin has decided to create three variations: a poodle, a bulldog, and a golden retriever. The company has indicated that they will consider adding additional breeds in the future. The breeds will have a set of common attributes and behaviors, but each breed may have some unique capabilities.

This presents some challenges for Viktor as he designs the software children will use to customize the dogs. He doesn’t want to write all of his code three times—once for each breed. He also doesn’t want future programmers to create new breeds that are not compatible with his original design. Since Viktor realizes that a poodle “is a” dog, and the same is true for the other breeds, Viktor decides to use inheritance.

1. In Viktor’s new design, Poodle, Bulldog, and GoldenRetriever are all: a. abstract classes b. base classes c. derived classes

2. To allow breeds to reuse code, and to help ensure that future breeds are compatible, Dog could be declared as: a. abstract

b. derived c. sealed

3. Which of the following are NOT going to be inherited

Base classes are referred to as “parent” classes or “superclasses;” derived classes are referred to as “child” classes or “subclasses.”

by the three derived classes? a. constructors

b. properties c. methods Understand inheritance

17

Answers 1. In this design, the three breeds are: c. derived classes

2. To take advantage of code reuse, the Dog should be declared as: a. abstract. Abstract classes cannot be instantiated, but implemented methods will be shared by all derived classes.

3. Which of these will NOT be inherited by the derived classes? a. constructors

Essential details • Inheritance allows you to create new classes that reuse, extend, and modify the behavior that is defined in other classes. • Derived classes inherit all the members of the base class, except for constructors and destructors. • Use the “is a” test to see if inheritance is appropriate. In Viktor’s case, a Poodle is a Dog, a Bulldog is a Dog, and a GoldenRetriever is a Dog; therefore, his use of inheritance is correct. However, a Tarantula is not a Dog, so if Tailspin decides to make robotic spiders, they’ll need a new base class. Otherwise, the spider would bark and wag its tail! • An abstract class cannot be instantiated.

Understand polymorphism SCENARIO: Viktor’s work with Tailspin Toys’ robotic dogs is progressing well. He knows that his software for personalizing the dogs will be popular with customers. Viktor feels that his basic class design ideas are good and he’s ready to think about the details, as long as the engineers and marketers stop making changes!

Viktor knows that while all dogs share some common behaviors, such as barking, that bark may be very different from one breed to the next. The Bark method he creates for a Poodle will need to be different from the Bark method he implements for a GoldenRetriever. In his Dog class, he’s created a few methods. Here are the headers, written in C#: public void Bark() { … } public void WagTail() { … } public void Walk() { … }

1. To be able to override these methods in the derived classes, what modifier should Viktor add to all three headers? a. new b. static c. virtual

2. How can Viktor invoke the Bark method in the Dog class from within a derived class? a. Bark() b. Dog.Bark() c. base.Bark()

3. What should Viktor do if he wants the Bulldog class to just use the Walk

Overriding a method allows a derived class to have its own implementation, different from other derived classes.

method from Dog? a. Implement Walk in Bulldog, copying and pasting the code from Dog b. Implement Walk in Bulldog and simply call Dog’s Walk method c. Do not implement Walk in Bulldog

Understand polymorphism

19

Answers 1. What modifier should Viktor add to the three methods? c. virtual

2. How can Viktor invoke the Dog’s Bark()method? c. base.Bark(). The base keyword is used to access members of the base class.

3. How should Viktor retain the base class’s Walk method in a derived class?

c. Do not implement Walk in Bulldog. No need to call base.Walk()—if a derived class does

not override an inherited method, the base class’s method will automatically be used.

Essential details • Important keywords: • base: Used to access members of the base class from within a derived class. • virtual: Allows a method’s implementation to be overridden in a derived class. • sealed: When applied to a class, prevents other class from inheriting from it; when applied to a member, prevents that member from being overridden by other classes. • new: When used as a modifier, this hides a base class member; the new member replaces the implementation in the base class. Note: This is different than the new operator used to instantiate an object! • override: Required to replace an inherited member. • The following C# code shows how Viktor can replace Dog’s methods in his derived d classes (assuming he corrects Dog as indicated by question 1):

public override void Bark() { … } public override void WagTail() { … } public override void Walk() { … } FAST TR ACK HELP

OBJECTIVE


Understand encapsulation SCENARIO: Viktor has done a great job designing software to customize Tailspin Toys’ robotic dogs. So great, in fact, that his boss wants to give him a promotion. Unfortunately, that means Viktor won’t be able to finish writing the software himself; instead, a new developer will take over the project. On the new developer’s first day, however, she accidentally sets the robot’s age to -237 and crashes the program.

To ensure that the new developer doesn’t damage code that already works, Viktor decides to “black box” the code he’s already implemented. This means that the new developer won’t need to see Viktor’s code, but will be able to use it as she continues the project. Viktor can also ensure that values are checked before any changes are made so that a dog doesn’t end up with a negative age.

1. Viktor has implemented several methods in the Dog class that he uses for Bark, such as OpenMouth and CloseMouth. He doesn’t want those methods to be called by any derived classes. Which access modifier should he use for those “black-boxed” methods? a. public b. protected c. private

2. Viktor’s primary methods, Bark, Sit, Walk, and WagTail should be accessible from anywhere in the project. Which access modifier should he use for those methods? a. public

b. protected c. private

3. Which of the following provides a means for reading and/or modifying private attributes? a. an interface

In C# and Visual Basic, properties provide “getter” and “setter” (also called “accessor” and “mutator”) functionality for instance variables.

b. a constructor c. a property Understand encapsulation

21

Answers 1. Which accessibility should Viktor’s “black boxed” methods use? c. private

2. Which accessibility level should Viktor use for his primary methods? a. public

3. Reading and/or modifying private attributes is provided by: c. a property

Essential details • This type of “black boxing” is often referred to as encapsulation. • In keeping with the principle of encapsulation, instance variables (attributes or fields) should be given the most restrictive accessibility level possible. That means making instance variables private whenever possible. • Instance variables of base classes are often defined as protected; this allows derived classes (such as the Poodle class) access to the data, while still hiding the data from other parts of the program. • One important reason for restricting access to data is to ensure validity when data is changed. Remember when the new developer tried to set the age attribute to a negative number? Likewise, the gender attribute should not accept a value of “green.” FAST TR ACK HELP

Understand application life-cycle management SCENARIO: Nupur has been named Project Manager of a new reservation system for Blue Yonder Airlines. She will lead a team of developers tasked with all phases of the application life cycle.

Napur and her team met with managers from each branch of the company and discussed the company’s needs and the basic features that everyone requires. The application will be web-based, and will allow Blue Yonder’s customers to search flights, book reservations, and check in online. After the meeting, Napur and her developers began outlining the program from their perspective. Although they haven’t begun coding, the developers are beginning to sketch out the classes and objects of the project using UML. Their outline is not complete, but a plan for accomplishing the required tasks is coming together. Napur wants to divide the job in such a way that team members can work on different parts of the program at the same time.

1. Napur’s meeting with the company’s managers is part of which stage of the application life cycle? a. Design b. Development c. Planning

2. The use of UML in this scenario: a. is a waste of time because they haven’t started writing code. b. helps ensure that different components will work together when finished. c. helps ensure that the clients understand how the team will create the software.

3. As the team writes code, Napur will ask each team to test their classes independently. What is this strategy called? a. Load testing

Developers may use different names for the stages or phases of managing the application life cycle, but the basic process is the same!

b. Unit testing c. Integration testing

Understand application life-cycle management

25

Answers 1. Napur’s meeting was the: c. Planning stage of the application life cycle. Planning (also called envisioning) includes gathering the client’s needs and requirements; in this case, the rest of the company is Napur’s client.

2. Napur’s use of UML: b. helps ensure that different components will work together when finished. The clients probably don’t need to know how to organize the actual development!

3. Testing individual components separately is called: b. Unit testing

Essential details • The phases of application life cycle management (ALM) are: planning, designing, developing, testing, and maintenance. • The ALM process is iterative, meaning that it repeats. When the application is deployed, new issues or feature requests are likely to come up, so the process starts again. • Notice that actually writing code (developing) is only a small part of the overall process. • UML stands for Unified Modeling Language. It provides a way to create visual models of the different components of an application. • Many programmers are familiar with “class diagrams” in object-oriented programming—these are generally drawn as UML diagrams.

Understand algorithms and data structures SCENARIO: Some time ago, Cassie agreed to help her soccer coach, Ken, keep track of the team by creating a software program especially for the task. The roster application will make it much easier for the coach to keep track of his players’ personal information and some simple statistics.

Now that Cassie has completed some initial planning, she needs to decide how to organize all of the data in her program. The application will need to keep track of many players, allowing the user to search through and pull up any individual’s data. And of course the coach will need to print a few reports, such as a complete roster sorted by jersey numbers, a phone list arranged alphabetically by the players’ last names, and the team’s leaders in goals.

1. Which of the following data structures would be a good choice for organizing the players? a. stack b. array c. linked List

2. Which of the following would help Cassie arrange the players in alphabetical order? a. a binary search b. a queue c. a bubble sort

3. Which data structure could Cassie use if she only wanted to retrieve players

Data structures are classes used to organize data and perform various operations upon that data.

using a “last in, first out” model? a. stack

b. queue c. linked List

Understand algorithms and data structures

29

Answers 1. The data structure Cassie should use is: b. array. Arrays are well-suited for programs that need to access the data in any order, as when the user performs a search.

2. Cassie will easily be able to put the collection into a specified order with: c. a bubble sort

3. The data structure that uses a “LIFO” pattern for adding and retrieving records is: a. stack

Essential details • Common data structures: • array: A list of data values or objects, all of the same type, any element of which can be referenced by an expression consisting of the array name followed by an indexing expression. • linked list: A list of nodes or elements of a data structure connected by pointers. Linked lists are great for collections that require many insertions in the middle of the list because such insertions simply require updating a couple of pointers. • queue: A structure from which elements can be removed only in the same order in which they were inserted; that is, it follows a “first-in, first-out” (FIFO) logic. • stack: A structure from which elements can be removed only in the reverse order in which they were inserted; this is referred to as “last-in, first-out” (LIFO). • A sort algorithm puts a collection of data elements into a sequenced order, sometimes based on one or more key values in each element.

Understand Web page development SCENARIO: Tanja owns a small dance studio and is looking for ways to bring in new customers and improve communications with her existing customers. She is not particularly knowledgeable about web design, but several years ago one of her dance students offered to create a website for the studio. That student has moved on to the university, so Tanja has relied on a few different volunteers to maintain the site. As a result, the site is disorganized and lacks consistency—the volunteers all used different colors and fonts that resulted in a very non-professional website.

Knowing that she can’t fix the site herself, she has asked her nephew, Maxim, to help. Before Maxim creates a page, he wants Tanja to have at least a basic understanding of the technology involved.

1. Which technology uses “tags” to indicate how information should be displayed in a web browser? a. HTML b. XML c. JavaScript

2. Which of the following is a key advantage of using CSS? a. It allows a web page to be interactive. b. It allows a site to incorporate multimedia clips, such as videos and music. c. It simplifies the formatting of multiple pages within a site.

3. What is JavaScript? a. a markup tag that manages various font settings b. a server-side technology for running Java applications

CSS stands for Cascading Style Sheet.

c. a client-side technology for making web pages interactive

Understand Web page development

33

Answers 1. What uses tags to specify how data should be displayed on a web page? a. HTML

2. An advantage of CSS is: c. It simplifies the formatting of multiple pages within a site.

3. JavaScript is: c. a client-side technology for making web pages interactive

Essential details • HTML stands for HyperText Markup Language and uses markup tags to specify how information should be displayed on a web page. • HTML tags are surrounded by angle brackets. The
tag indicates a paragraph. • Most HTML tags work in pairs—an opening tag and a closing tag. • CSS works in conjunction with HTML to indicate how data should be presented, including colors and fonts. • Although styles can be defined for an individual page, they can also be defined in a separate document and shared by each web page in a site. That means a developer can make a change to the CSS document and the look of the entire site will change! This makes it easy to ensure that each page in a site looks consistent. • JavaScript is a scripting language that allows developers to write code that goes beyond the markup limitations of HTML. • JavaScript is frequently used to make web pages more interactive. • Although JavaScript itself is a client-side technology, it is often used in conjunction with server-side technologies such as ASP.NET.

OBJECTIVE


Understand Microsoft ASP.NET Web application development SCENARIO: Maxim has spent quite a bit of time talking with his aunt, Tanja, about a new website for her dance studio and he is beginning to get ideas on how to update and improve the site. Tanja’s old site is pretty basic, and Maxim believes he can add a lot of exciting features that will appeal to younger, websavvy customers.

One of his first priorities is to make the site a little more interactive with buttons that respond to mouse rollovers and a slideshow to display images of the studio. He also wants to implement online shopping for dance apparel. That update would include a “wish list” feature for users to “save” items they’re interested in purchasing at a later time.

1. Maxim’s mouse rollover effect can be accomplished with a client-side script. Which of the following is a client-side technology? a. PHP b. ASP.NET c. JavaScript

2. In a standard HTML site, page information is lost each time the user refreshes a page or moves to a different page. Which of the following allows page information to be retained? a. state management b. page life cycle c. CSS

Client-side scripts are run by the user’s web browser.

3. Maxim wants to use cookies to keep track of users’ wish lists. What is a cookie? a. text data stored by the users’ web browser b. a back-end database for storing user information c. a server-side scripting tool for saving session data

Understand Microsof t ASP.NET Web application development

35

Answers 1. A client-side technology is: c. JavaScript

2. The process that allows page information to be retained is: a. state management

3. A cookie is: a. text data stored by the users’ web browser

Essential details • In a web application, a program or script can be either client-side or server-side. • A client-side script is downloaded by the user’s web browser and executed on that user’s computer (the “client”) when the page is loaded. • A server-side script is executed by the web server before the web page is sent to the user’s computer. • The event model in a web application is similar to that of a client application. One significant difference is that an event is raised on the client side (for example, when the user clicks a button), but the event is handled on the server side. • When an ASP.NET page runs, the page performs a series of processing steps in what is called the page life cycle. These steps include initialization, instantiating controls, restoring and maintaining state, running event handler code, and rendering. • State management refers to the process by which a developer maintains page information over multiple requests for the same or different pages.

Understand Web hosting SCENARIO: With plans for Tanja’s dance studio website beginning to take shape, it’s time for Maxim to think about how he will put the site on the Internet. Maxim doesn’t have a lot of experience creating web applications—most of his experience is with traditional Windows applications. He knows that a website is hosted on a server, but he’s never worked with a server before. Plus, his aunt doesn’t have a lot of money for this project, so he has to keep costs to a minimum until the site brings in some business.

1. Why is an ISP probably a good choice for Maxim? a. ISPs are always free. b. An ISP subscription includes a copy of Windows Server. c. The ISP will provide technical support and maintenance.

2. An employee at a reputable ISP tells Maxim that they use Windows Server and that he needs

to understand the basics of Internet Information Services (IIS). Which of the following is NOT a role of IIS? a. to deliver HTML documents to web browsers b. to enable server-side scripting, such as ASP.NET c. to enable client-side scripting, such as JavaScript

3. The ISP tells Maxim they support Virtual Directories. What is a Virtual

Directory? a. a folder on Maxim’s computer that maps to the ISP, so he can easily publish the site b. a directory name that maps to the physical location on the server c. a listing service that ensures that users can find the site with a search engine

Web hosting allows a developer to publish a website so that it is accessible via the World Wide Web.

Understand Windows Forms applications; Understand console-based applications SCENARIO: Julia doesn’t have a lot of free time while she’s studying computer science at her university, but in the evenings she enjoys playing online role-playing games (RPGs). She plays several games on a regular basis, and she enjoys “leveling-up” her characters and completing quests for special items.

However, because her playing time is both limited and fragmented, she has difficulty keeping track of the status of each of her characters. So she decides to create an application to keep track of the progress of her different characters, including levels and quests. She envisions a simple application that will allow her to select a character and then view and edit relevant information (a picture of the character, its current level, XP needed to advance, current quest item, and so on).

1. What type of application would best fit Julia’s needs? a. console application b. Windows Forms application implementing SDI c. Windows Forms application implementing MDI

2. For which one of the following situations would visual inheritance be useful? a. several different forms displaying the same data in different ways b. several different forms displaying data from tables in the same database c. several different forms using the same basic layout and UI features

3. Which of the following describes how the event model might function in Julia’s program?

SDI is Single Document Interface. MDI is Multiple Document Interface.

a. A Button click event is handled by code that creates a new character. b. A new character event is handled by code that asks for user input. c. A loop event cycles through the various characters, displaying each on the form.

Understand Windows Forms applications; Understand console-based applications

43

Answers 1. Julia should make a:

b. Windows Forms application with SDI. Although any application could work, SDI is ideal because the user only needs one window at a time. Note that a console application could not display images of Julia’s characters.

2. Visual inheritance would be useful when: c. Several different forms use same the same basic layout and UI features.

3. The event model could function in Julia’s program when:

a. A Button click event is handled by code that creates a new character.

Essential details • Windows Forms is a rich Windows client library for building Windows client applications. • A console application uses a text-only interface and usually requires only a keyboard for input. • The user interface is the portion of a program with which a user interacts. Different types of UIs include graphical user interfaces (GUIs), such as the Windows user interface, as well as command-line interfaces used by console applications. • The two basic styles of Windows interfaces are SDI and MDI. • Single Document Interface (SDI) is an interface in which each document frame window is separate from others and contains its own menu and toolbar. • Multiple Document Interface (MDI) is an interface in which multiple document ment frame windows may be open in the same instance of an application; the eside. application features a parent window in which multiple child windows can reside. • More recent applications tend to favor the SDI approach. gram • An event is an action or occurrence, often generated by the user, to which a program might respond. Examples include key presses, button clicks, and mouse movements. nts. • Code that is executed in response to an event is called an event handler. FAST TR ACK HELP

The store has thousands of albums by thousands of different artists, but the owner does not have an inventory system—he simply organizes the albums by artist on the store shelves. That means when a customer asks if a particular album is in stock, Jesper must go out to the shelves and look for the album.

Jesper wants to put together a simple inventory system so that he can look up which albums are in stock from a computer behind the counter. He’ll set up a relational database to store the information. He’ll start by giving each artist a random and unique Artist ID number. Likewise, each album will get an Album ID number.

1. What function do Artist ID and Album ID fulfill in Jesper’s relational database, as described above? a. relationships b. constraints c. primary keys

2. Jesper will link albums to artists by adding an Artist ID field to his Albums table. In this Albums table, what is the Artist ID? a. primary key b. foreign key c. link key

3. Which of the following will result from the use of a relational database for this project? a. minimize or eliminate redundant (repetitive) data

There will be two tables in the database: Artists will store artist information; Albums will hold data related to individual albums.

b. increase processing time resulting from inefficient storage of data c. require the use of a web server

Answers 1. Artist ID and Album ID are: c. primary keys

2. The Artist ID field in the Albums table is a: b. foreign key. A foreign key from one table (Albums) refers to a primary key in another table (Artists). This establishes a relationship between the two tables.

3. The use of a relational database in this project will: a. minimize or eliminate redundant (repetitive) data

Essential details • A relational database is a system for storing potentially large amounts of data. Relational databases consist of one or more tables that can be visualized as columns and rows. • One of the primary advantages of a relational database is the reduction of data redundancy—data in multiple tables can be linked instead of stored twice. • In a table, a primary key defines a column that uniquely identifies each row. • A relationship can be established by setting up a foreign key constraint. Each album in the store includes the corresponding Artist ID. That foreign key establishes a link between the album and the artist who recorded it. FAST TR ACK HELP

OBJECTIVE


Understand database query methods SCENARIO: Now that Jesper has designed and implemented a relational database to keep track of the inventory at the record shop, he needs to be able to read and modify the data itself. He’ll use SQL queries for his database operations.

The application must enable Jesper to add to the database when the store gets a new album, and to modify data such as the quantity in stock and the price. Additionally, he will need to pull data from the database: find artists or albums, list the current inventory, and list albums that are currently out of stock. Reviewing SQL concepts will help Jesper quickly complete the project.

1. Which SQL command should Jesper use to add a new album to his database? a. ADD b. INSERT c. UPDATE

2. Jesper can save frequently used queries as: a. UPDATE files b. database methods c. stored procedures

3. Which query could retrieve the artist “U2” from the table of artists? a. SELECT “U2” FROM Artists b. SELECT * FROM Artists WHERE ArtistName = “U2” c. SELECT * FROM Artists WHERE “U2” IN ArtistName

SQL stands for Structured Query Language and is used to execute most common actions on a relational database.

Answers 1. A new row can be added to the database with: b. INSERT

2. Queries can be saved to the database as: c. stored procedures

3. “U2” can be retrieved from the table of artists with: b. SELECT * FROM Artists WHERE ArtistName = “U2”

Essential details • Structured Query Language (SQL) is used to manage data in a relational database. • SQL queries can be used interactively with the database itself or implemented in an application that accesses the database. Basic statements in SQL queries include: • SELECT to retrieve data • INSERT to add rows to the database • UPDATE to modify existing rows • DELETE to remove an existing row • Other clauses can be added to indicate the desired table (FROM), to filter data based on comparisons (WHERE), and to sort (ORDER BY), among others.

OBJECTIVE


Understand database connection methods SCENARIO: With a solid database design in place and a few stored procedures to help manage his SQL queries, Jesper turned his attention to a user interface for his application. Using Windows Forms, he now has the essential elements in place to connect his application to the database.

Jesper decides to use a “disconnected” approach, meaning that he will copy what he needs from the database to memory, then disconnect from the database. When the user changes data, the application can connect again and update the database.

1. What is the advantage of Jesper’s use of a disconnected data access model? a. It minimizes the impact on the database server. b. It does not require an Internet connection. c. It prevents unauthorized access to the database.

2. What is the term used to describe an in-memory cache of the database? a. dataset b. XML c. OLE DB

3. What object contains the information ADO needs to connect to a database? a. SQL Query b. file path c. connection string

ActiveX Data Objects (ADO) is an interface that allows developers to access databases without worrying about details of database connections.

Answers 1. An advantaged of using a disconnected data access is: a. It minimizes the impact on the database server.

2. The name of the in-memory database object is: a. dataset

3. The information needed to connect to a database is stored in the: c. connection string

Essential details • To bring data into your application (and send changes back to the data source), a two-way communication path needs to be established. This connection is usually configured with a connection string that stores information necessary to find and access the data source. • Data sources don’t have to be relational databases. • Extensible Markup Language (XML) files are common on the Internet. They share the same syntax as HTML, so many users are comfortable working with them. • Language Integrated Query (LINQ) allows developers to connect to a wide range of data sources, including arrays and other data structures. • Flat files are conventional computer files that store database information. • Many developers use a disconnected data access model. By connecting to a data source only as long as it takes to retrieve or update data, the developer gains several advantages: • Reduced load on the database server. • Scalability, or the ability to continue to function as the work load increases. • Multiple users can access the same database without “locking” file access.
