📚 Java Library Management System

A Library Management System built using Java, designed to simplify the management of books, students, and borrowing records. This project demonstrates strong use of Object-Oriented Programming (OOP) principles, file handling, and collection frameworks in Java.

---

🚀 Overview

This console-based system enables users to efficiently manage library operations such as adding books, registering students, issuing and returning books, and viewing all records. It’s ideal for understanding how core Java can be used to build real-world, menu-driven applications.
