LibraryManagementSystem

A Java-based console application for managing a library.

Overview

The Library Management System is a console-based Java application designed to manage a library's books, users, and borrowing transactions. It demonstrates object-oriented programming (OOP) principles, file handling, and data persistence using CSV files. This project showcases modular, production-ready code suitable for a Software Development Engineer (SDE) portfolio.

Features

• Book Management: Add, update, and view books in the library.
• User Management: Register and manage library users.
• Borrowing System: Allow users to borrow and return books, with availability tracking.
• Data Persistence: Store books, users, and transactions in CSV files.
• Error Handling: Robust input validation and error management.

Technologies Used

• Language: Java 17
• Concepts: OOP (Encapsulation, Inheritance, Polymorphism), File I/O, ArrayList, Exception Handling
• Data Storage: CSV files

Setup Instructions

1. Clone the Repository:

   git clone https://github.com/AmSh4/LibraryManagementSystem.git
   

2. Compile and Run: Ensure Java 17 is installed. Compile the project:

   javac -d bin src/*.java src/model/*.java src/service/*.java
   

Run the application:

java -cp bin Main

3.Interact with the Application: Use the console menu to add books/users, borrow/return books, or view the book list.

Dataset

The data/ directory contains large datasets to demonstrate scalability: books.csv: Stores 50 book records (ID, title, author, availability). users.csv: Stores 20 user records (ID, name). transactions.csv: Stores 30 borrowing records (book ID, user ID, borrow date, return date).

Usage

Run the program and select options from the menu: Add a new book to the library. Register a new user. Borrow a book (requires book ID and user ID). Return a borrowed book. Display all books with their availability status. Exit the application.

Future Enhancements

Add a GUI using JavaFX or Swing. Implement a database (e.g., MySQL) instead of CSV files. Add user authentication and role-based access (e.g., admin vs. user). Generate detailed reports (e.g., overdue books).
