📚Library_System

This project is a command-line interface (CLI) program for managing a library's system. The program is written in Java and provides the following menu options:

• B - Manage Book Repository: Allows the user to add, remove, print, and sort books in the library's repository based on specific criteria, such as ISBN number, book name, author name, genre, year, and condition.
• C - Checkout Book: Allows the user to checkout a book from the library by entering the book's ISBN number.
• N - Add New Book: Allows the user to add a new book to the library's repository by entering the book's details, such as ISBN number, book name, author name, genre, year, and condition.
• R - Remove Book: Allows the user to remove a book from the library's repository by entering the book's ISBN number.
• P - Print Repository: Allows the user to print the entire book repository or a subset of it based on specific criteria, such as ISBN number, book name, author name, genre, year, and condition.
• S - Sort Shelf: Allows the user to sort the books in the library's repository based on specific criteria, such as ISBN number, book name, author name, genre, year, and condition.
• Return Commands
• R - Manage Return Stack: Allows the user to manage the return stack, which stores the books that are returned to the library.
• R - Return Book: Allows the user to return a book to the library by entering the book's ISBN number.
• L - See Last Return: Allows the user to see the last book that was returned to the library.
• C - Check In Last Return: Allows the user to check in the last book that was returned to the library.
• P - Print Return Stack: Allows the user to print the entire return stack or a subset of it based on specific criteria, such as ISBN number, book name, author name, genre, year, and condition.
• Q - Quit: Allows the user to quit the program.
