Design an interface named Colorable with a voidmethod named howToColor(). Every class of a colorable object must implementthe Colorable interface. Design a class named Square that extendsGeometricObject and implements Colorable. Implement howToColor todisplay the message Color all four sides. The Square class contains adata field side with getter and setter methods, and a constructor for constructinga Square with a specified side. The Square class has a private double datafield named side with its getter and setter methods. It has a no-arg constructorto create a Square with side 0, and another constructor that creates a Squarewith the specified side.Draw a UML diagram that involves Colorable, Square, and GeometricObject.Write a test program that creates an array of five GeometricObjects. For eachobject in the array, display its area and invoke its howToColor method if it iscolorable.
