Library Management System

A small-scale Java project that simulates a library management system using Object-Oriented Programming (OOP) concepts and Java Collections.
This project allows users to manage books and library members, including adding, listing, searching, borrowing, and returning books — all through a simple console-based interface.

Features

Book Management

• Add new books with title and author.

• Users can borrow available books.
• Users can return borrowed books.
• Book availability is tracked automatically.

Console Menu Interface

• Easy-to-use menu-driven system for interacting with the library.

Technologies Used

• Java – Core programming language.
• OOP Concepts – Classes, Objects, Encapsulation, Methods.
• Collections Framework – ArrayList for storing books and users.
• Console I/O – Scanner for user input.

How to Run

1. Clone the repository:

git clone https://github.com/sumitojha2002/Library-management-system.git

2. Navigate to the project folder and compile the code:

   javac models/.java services/.java Main.java

3. Run the program: java Main

4. Follow the on-screen menu to add books, add users, borrow/return books, and search.

Future Improvements

• Save data persistently (file or database) so data is not lost on exit.
• Improve input validation for better user experience.
• Add advanced features like overdue tracking, categories, or multiple copies of books.
• GUI interface using JavaFX or Swing.
