Area Calculation Using Function Overloading in java

 

class ShapesArea

{

    void area(double r)

    {

        System.out.println(Math.PI*Math.pow(r, 2));//circle

    }

    void area(int a)

    {

        System.out.println(Math.pow(a, 2));//square

    }

    void area(int x,int y)

    {

        System.out.println(x*y);//rectangle

    }

    void area(int p,int q,int r)

    {

        double s = (p+q+r)/2;

        System.out.println(Math.sqrt(s*(s-p)*(s-q)*(s-r)));

    }

}
