Core Java Assignment 5

 java Language Lab Assignment Assignment 3 -------------------------------------------------------------------------------1. Define a base class person and a derived class employee with single inheritance. - Define SetData! member functions in each of the class with different signatures to set the members and demonstrate overloading of member functions.

data

- Define "etData! member functions in each of the class with same signatures to display data and demonstrate overriding of member functions. #. $odify program 1 to define a parametri%ed constructor and finali%er in each class. Demonstrate calling the constructor constructor of the base class from the constructor of the derived class. - &reate objects of person and employee classes to show the order of invocation of constructors. 3. $odify program # to define another class manager that derives from employee' to create a chain of multilevel hierarchy.manager inherits from employee ( employee inherits from person! - &reate objects of person' employee' and manager classes to show the order of invocation of constructors. ). $odify program # to define define another class student student that derives from person' person' to create a hierarchial inheritance.employee inheritance.employee and student inherit from person! - &reate objects of person' employee' and student classes to show the order of invocation of constructors. *. +rite a java file ,erson.java containing definition definition of independent class ,erson in pacage com.person' and another java file Address.java containing definition of independent class Address in com.address  pacage. - +rite a container class employee that has a person and an address object as contained data members besides other data members! by importing the above pacages. - Demonstrate the passing of arguments in the constructors of person and address classes by the constructor of the employee class. . /ewor program * to use both inheritance and containership. 0he employee class inherits from person class and acts as a container class for address class object. . +rite a program to demonstrate the use of try' catch' finally throw and throws eywords and demonstrate the following points in the program. a! $ultiple catch blocs.  b! try-catch-finally combination. combination. c! try-finally combination. d! 2ception propagation among many methods. e! 4se of get$essage!' printStac0race! function of 0hrowable class. f! 5ested try blocs 6. +rite a program to throw a checed eception eplicitly using 7throw7 eyword and a! 8andle the eception in same method.

 b! use throws clause and handle the eception in some other method calling method! c! Don7t either handle or use the throws clause. 9bserve the result. :. /epeat program 6 with uncheced 2ception and demonstrate the difference in both program. 1;. &reate a user defined eception to chec whether your employee eist in your data structure use any data structure to store the employees - lie array' ArrayList etc! and throw eception if name is not in the employees list. 4se the catch and finally bloc to mae an appropriate solution. 11. +rite a program to demonstrate the use of enteger class 9bject. 4se the override enteger with two different object wrapping same primitive int value  lie - 1;!.demonstrate the difference in the output from  program 11. 13. Demonstrate the use of ceil!' floor!' round!' random!' abs!' ma!' min! methods of $ath class. 1). +rite a program to invoe garbage collector and show the details of free memory before and after the garbage collection. 1*. +rite a program to print all System properties using system class. 1. Define a method set$y,roperty String' String! to set your own system property and use the same system property in another method. NOTE : Core Java Assignments 3 will be checked on 07//!0!
