Q 05) Over Loading

      Two or more methods in the same class with “ SAME NAME ” But their parameter declarations are different, This is called as overloading.

·       It shows the implementation of polymorphism.

·       Static Polymorphism is achieved by method overloading.

Two Rules of Overloading:

• Argument list must differ.
• Return types cannot be different.  

Example Program of Over Loading  :

package org.javanoobs.overloading;

public class CalculateSum {

    

     void findSum (int a, int b){

          

           int twoSum = a+b;

           System.out.println(" Result of int a + int b :  " +twoSum);

          

     }

    

     void findsum (int a , double b){

          

           double twoSum = a +b;

           System.out.println(" Result of int a + double b :  "+twoSum);

          

     }

    

     void findSum (double a, double b){

          

           double twoSum = a + b;

          

           System.out.println("Result of double a + double b :  " +twoSum);

          

     }

    

    

     public static void main (String args[]){

          

          

      CalculateSum cs = new CalculateSum();

      

      cs.findSum(10, 20);

      cs.findsum(10, 20.22);

      cs.findSum(22.34, 32.98);

     }

}

OUTPUT:

Result of int a + int b :  30

Result of int a + double b :  30.22

Result of double a + double b :  55.31999999999999
