Area Calculate in Java.

Main Class:

 

package pkg2;

public class Main {

    public static void main(String[] args) {

        AreaCalculator A = new AreaCalculator();

       

        System.out.println("Area of Circle: "+A.getArea(5.5));

        System.out.println("Area of Triangle: "+A.getArea(5,6));

        System.out.println("Area of Cylinder: "+A.getArea(56,10));

    }

}
