Code of Library Management System

We’ve gone over the different aspects of the library management system and observed the attributes attached to the problem using various UML diagrams. Let us now explore the more practical side of things, where we will work on implementing the library management system 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 library management system:

• Java

• C#

• Python

• C++

• JavaScript

Library management

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

First, we will define all the enumerations required in the library management system. According to the class diagram, there are four enumerations used in the system: BookFormat, BookStatus, ReservationStatus, and AccountStatus. The code to implement these enumerations is as follows:`

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.
