Step $1$: Create the Book Class

Objective:

The Book class models a book in the system with attributes like title, author, barcode, and status $($whether it$$s checked out or not$)$

Code:

$/**$

$*$ Book class to represent each book in the Library Management System.

$*$ Author: $[$Your Name$]$

$*$ Course: $[$Course Name$]$

$*$ Date: $[$Date$]$

$*/$

public class Book $\{$
