Code for the Chess Game

We've covered different aspects of the chess game and observed the attributes attached to the problem using various UML diagrams. Let's now explore the more practical side of things where we will work on implementing the chess game 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 chess game:

  • Java

  • C#

  • Python

  • C++

  • JavaScript

Chess game classes

In this section, we will 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 and custom data type

The following code provides the definition of the enumeration and custom data type used in the chess game.

GameStatus: This enumeration keeps track of the active status of the player and the game, i.e, who wins and whether or not the game is a draw.

AccountStatus: We need to create an enumeration to keep track of the status of the account – whether it is active, canceled, closed, blocked, or none.

The Person class is used as a custom data type. The implementation of the Person class can be found below:

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.
