Write a class named Octagon that extends GeometricObject and implements the Comparable and Cloneable interfaces. Assume all eight sides of the octagon are of equal length. The area can be computed using the following formula: area = (2 + 4/(sqrt(2)) * 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 of zero length, and a constructor to create an Octagon with a specified side. Write a test program that creates an Octagon object with side value 5 and displays its area and perimeter. Create a new Octagon object using the clone method, and compare the two objects using the compareTo method.

Write a class named Octagon that extends GeometricObject and implements the Comparable and Cloneable interfaces.
Assume all eight sides of the octagon are of equal length. The area can be computed using the following formula:
area = (2 + 4/(sqrt(2)) * 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 of zero length, and a constructor to create an Octagon with a specified side.
Write a test program that creates an Octagon object with side value 5 and displays its area and perimeter. Create a new Octagon object using the clone method, and compare the two objects using the compareTo method.
