Library Management System

• This project is a simple Java-based library management system that allows librarians and library members to manage books, members, and book borrowing and returning operations. It consists of three main classes: Book, Member, and Library, as well as a Main class for user interaction.
• This library management system allows for efficient management of books and members, tracks borrow times, enforces borrowing limits, and calculates fines for overdue books, ensuring smooth library operations.

How to run the code

• variable phone number is in long type which accepts only 10 digits numbers which are standard in india.
• age as an integer value
• each choice prints according to what was written in the Assigment 1 Document and things which were not specifically written are being done according to the sample or how i thought it would be appropriate.

Implementation

• The library management system is implemented using Java and follows an object-oriented approach. Here's a brief explanation of each class:

Book Class

• Represents a book in the library.
• Contains attributes for book ID, title, author, number of copies, and availability status.
• Provides methods to get and set book details, check out a book, return a book, decrement the number of copies, and increment the number of copies.
• The toString method is overridden to display book information.

Member Class

• Represents a library member.
• Contains attributes for member ID, name, age, phone number, fines, and a list of borrowed books.
• Provides methods to register a member, borrow a book, return a book, calculate the time a book was borrowed, get and set member details, add fines, remove fines, reset fines, and display member information.
• Uses a map to track borrowed books and their borrow times.

Library Class

• Represents the library itself and manages its operations.
• Contains lists of books and members.
• Provides methods to add books, register members, list available books, list members with fines, find a member by name and phone number, find a book by ID, remove a member, and remove a book.
• Ensures constraints like not allowing a member to borrow more than two books or checking fines for overdue books.

Main Class

• Handles user interaction through the command line.
• Offers options for librarians and members to perform various operations, such as registering members, adding/removing books, listing books/members, borrowing/returning books, and paying fines.

Features/Functions

Librarian Functions:

• Register a new member.
• Remove a member (if no books are borrowed and no fines are pending).
• Add a book to the library.
• Remove a book (if it's available).
• List all members along with their borrowed books and fines.
• List all available books in the library.

Member Functions:

• List available books.
• List books borrowed by the member.
• Borrow a book (if eligible and available).
• Return a book (calculating fines for overdue books).
• Pay fines (if any).

How Functions Are Related

• The Library class serves as the central component that manages books and members.
• Librarians can interact with the library to add/register members and add/remove books.
• Members can borrow and return books, check their fines, and see available books.
• The Book and Member classes contain methods specific to book and member operations, while the Library class orchestrates these operations.
• The Main class provides a user-friendly interface for both librarians and members to interact with the library system.
