METHOD OVERLOADING

1. method with same  name but different parameter list or return type are called overloaded method
2. the overloaded method can be in same class or extended class.It is one of the way of polymorphism in java

PROGRAM:

````````````````

class a 

{ 

void test() 

{ 

System.out.println("No parameters"); 

} 

// Overload test for one integer parameter. 

void test(int a) 

{ 

System.out.println("a: " + a); 

} 

// Overload test for two integer parameters. 

void test(int a, int b) 

{ 

System.out.println("a and b: " + a + " " + b); 

} 

// overload test for a double parameter 

double test(double a)

{ 

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

return a*a; 

} 

} 

class ab

{ 

public static void main(String args[]) 

{ 

a ob = new a(); 

double result; 

// call all versions of test() 

ob.test(); 

ob.test(10); 

ob.test(10, 20); 

result = ob.test(123.2); 

System.out.println("Result of ob.test(123.2): " + result); 

} 

}

OUTPUT:

~~~~~~~

No parameters

a: 10

a and b: 10 20

double a: 123.2

Result of ob.test(123.2): 15178.240000000002
