Exercise: Exercises 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: 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. 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 compareTo method. As far as classes go, the abstract GeometricObject class contains the abstract doubles getArea() and getPerimeter(). The programming language used in this exercise is Java, and it covers the Interfaces topic. I did get how most of the program should look like, but I'm facing trouble understanding a few concepts, so I will appreciate an explanation.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
