Java program to demonstrate concept of Polymorphism by function overloading.

class Overloaddemo

{

 

void test ()

  {

   

System.out.println ("No Parameters");

 

}

void test (int a)

  {

   

System.out.println ("a:" a);

 

}

void test (int a, int b)

  {

   

System.out.println ("a & b:" a " " b);

 

}

double test (double a)

  {

    System.out.println ("Double a:" a);

   

return a * a;

 

}

}

class Overload

{

 

public static void main (String args[])

  {

   

Overloaddemo ob = new Overloaddemo ();

   

double result;     

    ob.test (10);

   

ob.test (10, 20);

   

result = ob.test (123.25);

   

System.out.println ("Result of ob.test(123.25):" result);
