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.
Draw a UML diagram that involves Colorable, Square, and GeometricObject.
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.
