Java Program:

Design an interface named Colorable with a void method named howToColor(). Every class of a colorable object must implement the Colorable interface. Design a class named Square that extends GeometricObject and implements Colorable. Implement howToColor to display the message Color all four sides. The Square class has a private double data field named side with its getter and setter methods. It has a no-arg constructor to create a Square with side 1 and another constructor that creates a Square with a specified side.

Write a test program that creates an array of five GeometricObjects. For each object in the array, display its area and invoke its howToColor method if it is colorable.
