Library-Manager

A simple console-based Library Management System written in Java.
This project allows users to manage a local file-based database of books using plain text files. It simulates real-world operations such as:

  • ✅ Adding new books
  • 🔍 Finding a book by ISBN
  • 🔄 Updating a book’s quantity
  • ❌ Removing a book by ISBN
  • 📃 Viewing the entire book collection

🗂️ Book Format

Each book is stored in library.txt in the following format:

Id: 978-3-16-148410-0
Name: Clean Code
Author: Robert C. Martin
Genre: PROGRAMMING
Avaible: 5
---

Books are separated by "---" to mark the end of an entry.

🧠 Technologies Used

  • Java Core
  • BufferedReader & BufferedWriter
  • Enumerations (enum)
  • Console-based user input with Scanner
  • File I/O for persistence

▶️ How to Run

  1. Clone the repository or download the files:

    git clone https://github.com/YOUR_USERNAME/LibraryManager.git

  2. Make sure the project structure looks like this:

    LibraryManager/
└── librarymanager/
    ├── BookType.java
    ├── LibraryEntrance.java
    ├── LibraryManager.java
    ├── Main.java
    └── library.txt

  3. Compile the source code:

    javac librarymanager/*.java

🚀 Contributions & Future Ideas

You can improve this project by:

  • Adding encryption for secure storage
  • Creating a GUI with JavaFX
  • Migrating to a database (like SQLite)
  • Implementing search/filter by name or author
