How do you implement inheritance in Java?

Short answer from interview point of view inheritance is implemented by using "EXTEND"keyword. As discussed in the previous basic definitions of OOP's inheritance is used to define more specialized class below the hierarchy. To understand this better lets do a small project to get the actual feel of the same.

Below is the project structure of the "Inheritance" project. It has the three classes:

 "ClsAdd java"

This class has a basic subroutine which adds two numbers. V "ClsSpecialAdd.java"

This class inherits from "ClAdd.java" and overrides the subroutine which does the basic addition. It changes the basic addition functionality by adding an extra adjustment value of "20",

"ClsRun java"

This is the class which has the "public static void main (String ] args)" method. It's the main class

which will run the whole show by creating the objects of "ClsAdd" and "ClsSpecialAdd" and executing the "Add" method.
