OOP's Polymorphism

 It provides different services but the same name/domain.

Polymorphism is implemented by method overloading.

Example : 

class ploy{

    public static void main (String[] args){

        ploy obj = new ploy();

        obj.arae(10);

        obj.area(5,3);

    }

    void area(int a){

        System.out.println("area 1 : " + a*a);

    }

    void arae(int a, int b){

        System.out.println("area 2 " + a*b);

    }

}
