Object Oriented Programming

 

Q. What is inheritence in Object Oriented Programming ?

Ans:  Inheritence is a mechanism through which one object occupies the state and behaviour of its parent object and can also add new state and behaviour of its own. Inheritence represents IS-A realationship. Inheritence is used to attain code reusibility and runtime polymorphism in java.

        class Byke

        {

                String vehicle_no;

                String  reg_no;

               public void running()

               {

                       System.out.println(Byke running);

               } 

         }

         class Honda extends Byke

          {

                     String current_gear;           

                     String curr_speed;

                     String color;                   // Existing properties+new properties

                     String no_of_gears;

                     public void applBreak()

                      {

                                System.out.println("Applying break");

                      }  

          }
