Lab 2B: Abstract Classes and Interfaces
Objectives
To write a program using classes to demonstrate how abstract classes and interfaces are implemented using code.
Problem Statement
Write a class named Octagon that extends the abstract class GeometricObject and implements the interfaces Comparable and Cloneable. Assume that all eight sides of the octagon are of equal size. The area can be computed using the following formula:
area = (2+4/sqrt(2))*side*side
Write a test program that creates an Octagon object with the side value 8 and displays it’s area and perimeter (to 2 decimal places). Create a new object using the clone method and create a method that compares the two objects (Octagon object and clone object) and returns true if all data elements are the same in both objects, false if any data object is different.
