Code of Jigsaw Puzzle

We’ve gone over the different aspects of the jigsaw puzzle and observed the attributes attached to the problem using various UML diagrams. Let’s explore the more practical side of things, where we will work on implementing the jigsaw puzzle using multiple languages. This is usually the last step in an object-oriented design interview process.

We have chosen the following languages to write the skeleton code of the different classes present in the jigsaw puzzle:

• Java

• C#

• Python

• C++

• JavaScript

Jigsaw puzzle

In this section, we’ll provide the skeleton code of the classes designed in the class diagram lesson.

Note: For simplicity, we are not defining getter and setter functions. The reader can assume that all class attributes are private and accessed through their respective public getter methods and modified only through their public method functions.

Enumerations

The following code defines the Edge enum that represents the shape of the puzzle piece:

Note: JavaScript does not support enumerations, so we will be using the Object.freeze() method as an alternative that freezes an object and prevents further modifications.
