OOP Programming Task 1 Introduce oop concepts Object-oriented programming this is a technique used to create real-world entities around the program. OOPS programming model, program development around the objects and data rather than actions and logic. Oh, every real life objects properties and behaviors. 

Objects and classes



Inheritance



Polymorphism



Encapsulation



Abstraction

Classes A class defines the properties and behavior (variables and methods) is shared by all objects. This is a blueprint to create an object.

Objects The object is the object-oriented programming language entity. The class itself has nothing to do but the real functionality through its object. The object is an instance of the class. Its attributes (variables) and behavior (methods) defined in the class.

OOP Programming Inheritance Inheritance allows a class (subclass) to obtain another class of properties and behaviors of (ultra). In Java, a class can inherit only o nly one class (parent class) at the same time, bu t a class can have an y number of subclasses. It helps to reuse, customize, an d strengthen the existing code. Therefore, it helps to write code and reduce development time. Java uses extend keyword to extend the class.

Polymorphism Polymorphism allows an interface will be used as a set of actions. A name, may be related to different functions. Polymorphism allows objects to accept a client (and th en the correct interpretation of requirements, such as selecting the appropriate method), the different requirements based on the current state of the runtime system response, did not disturb the user.

OOP Programming Encapsulation Package together a single entity and the process of data variables. This makes the function code security of data and from the outside world. Hidden in the data of the class, it is only through the method.

OOP Programming Assumptions 

Patient This pharmacy has a lot of customs so they have to give a id so it is easy to search, in here the is the person s NIC because it is unique to every person



Physician This is the people who work in the pharmacy. in here all the necessary information about the works are includes



Order Before buying the drugs customs need to order the product



Drug In here all the drug information like drug id e tc.. are includes



Supply This entity has the supply name, supply id,supply tell etc..

Log In After entering the correct User name and the password, the librarian has to click this button. When this button is clicked, this security form will disappear and th e main menu will appear. Exit This button is used to exit from the system. When it is clicked, a confirmation message appears asking the librarian if he is sure about the command he has given.

In the main menu we can choose system functions such as patient Information , Emplo yee Information , Drug Information And sales Information . Patient Information : When we click this button we get the patent’s information . In here we can add new patients and remove old patients information . Employee Information : When we click this button we can get the Employees Information , In here we can add information about employees and remove the old information . Drug Information : When we click this button we can get details about drug information . Here we can add information and remove information about drugs . Sales Information : When we click this button we can get information about the drug sales we have done . Help : when we click this button u will get the help menu

OOP Programming Task 6 OOP Object relations IF and Else

While

An object-oriented system can be used as the system characteristics of the partner. Some object with some other objects to interact, or only a specific set of objects. Sometimes object con sidered as equivalent, even though there may be of them. That specific differences Instead, system designers may want to commonalities between the expression of apples and oranges. An oriented object system, there are two different mechanisms to ex press the concept of these relationships: "Yes," which is technically known as "inheritance" and "This is technically known as" component ".

Task 7 How the OOP concepts are used in java Modularity The Java programming language provides man y features to support the construction of large projects, but can do more to reduce JAR hell and simplify application packaging. This talk will describe how the modular program can solve these problems, and how to design the functionality of the Java language and virtual machine can make the program more modular, while retaining compatibility with legacy code.

OOP Programming

Re-usability Java's reusable means that, once you write some code, you can use it again - if you write so that it can be reused.

Maintainability Programmers need to be precise. If you are sloppy and inconsistent space indent, name, or the access modifier of confidence in your logic is any more accurate. A of the framework, developers can sometimes help to avoid you do not have to reinvent the wheel every time, but a bad frame is infinitely better than no framework at all worse. Well-designed framework is very, very hard. Carefully consider this and draw their o wn conclusions. Test your code, and keep testing. Automated unit testing is very useful, especially the program or d river module from the command line. The other hand, trying to automate GUI testing is a noble goal, but is usually doomed to failure. Has a very small return, which requires a lot of effort. The production test is very "brittle". Keep the code simple and understanding. Source code, no one understands, if there is no file, no source code, a bug-ridden does not support third-party library is useful, think abo ut your reward structure. If you reward the length of their file systems analysts, programmers, lines of code written for them, day, they can invoice the number of consultants, and they hired the size of the team manager, then the collective would be powerless to reduce the size or development costs. Do not optimize too early. Unless you do the I / O or perform the same operation a million times or more, forgot to optimize it, until your nex t run the program analyzer. Tharuka Silva HND/49/07

In this interface show how the system button are working and there functions

This error comes when the system is not conne cted to the my sql

OOP Programming

After clicking the patient information on the main menu this will display and from this we can enter patient in formations, edit patient information’s, delete patient information’s and search patient information’s. and all so this interface shows all the patient information’s of the pharmacy

After clicking the Sales information on the main menu this will display and from this we can enter Sales information, edit Sales information, delete Sales information and search Sales information by invoice id and all so this interface shows all the Sales information of the pharmacy


Page 23

OOP Programming

After clicking the Drug information on the main menu this will display and from this we can enter Drug information, edit Drug information, delete Drug information and search Drug information by id and name, and all so this interface shows all the Drug information of the pharmacy

After clicking the employee information on the main menu this will display and from this we can enter employee information, edit employee information (when the details are change ), delete employee information and search employee information b y id and name, and all so this interface shows all the employee information of the pharmacy

After clicking the Help on the main menu this will display and it will give a ll the actives done by buttons


Page 25

OOP Programming Future Recommendation 

In the future this can be converted in to wed basic system which will give more access to the owner of the pharmacy



The data base can be go to a higher version of My SQL from older one



This can be made a online store so the customers can order goods online



The login can be generated by a biometric screener so it is more secure then the password protection



More detail report can be generated

OOP Programming Conclusion Here, I have to do this document very carefully; other hand, I do a good running program on the allocation request. According to this problem, I made a successful system. In this assignment i had made a system for the "Medi friends pharmacy". Through scenarios, I made a comfortable system. In all the many problems I do this task during the period, in the face, but I'm trying to solve the whole problem and related to OOP concepts, I got a good idea. One last thing to mention is that I try to give a nice interface. But it is still a command interface and users prefer GUI-based point, and then click interface. If this is such an application, it will be more and more system attractive to users. In this softer ware it is very easy to understand and to any person, its very user-friendly and In this programs some buttons are not working
