Programming Exercise 13.7 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 contains a field side with its getter and setter methods. The class has a constructor for constructing a Square with a specified side, and a no-arg constructor that creates a Square with side 0. 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
