Library Management System

A console-based Library Management System built in Java, demonstrating core Object-Oriented Programming (OOP) and Data Structures & Algorithms (DSA) principles.

---

Project Overview

This system simulates a real-world library management workflow. It allows librarians to manage books, handle member registrations, issue and return books, and track availability — all via a clean, menu-driven console interface built with Java OOP principles.

Features

• ➕ Add / Remove Books — manage the library catalogue
• 👤 Member Registration — add and manage library members
• 📖 Issue & Return Books — track book lending with due dates
• 🔍 Search Books — search by title, author, or ISBN
• 📋 View All Records — list all books and members
• ⚠️ Availability Check — real-time book availability status
