*13.11 (The Octagon class) Write a class named Octagon that extends Geometricobject and implements the comparable and Cloneable inter- faces. Assume all eight sides of the octagon are of equal length. The area can be computed using the following formula: area = (2 + 4/V2) * side * side The Octagon class has a private double data field named side with its getter and setter methods. The class has a no-arg constructor that creates an Octagon with side 0, and a constructor to create an Octagon with a specified side. Draw the UML diagram that involves Octagon, GeometricObject, Comparable, and Cloneable. Write a test program that creates an Octagon object with side value 5 and displays its area and perimeter. Create a new object using the clone method, and compare the two objects using the compare to method
