Library Management Server

A simple Java-based Library Management Server that allows you to manage books, members, and borrowing records through a web browser.

The project uses plain Java, the built-in com.sun.net.httpserver.HttpServer for a lightweight HTTP server, and a single-page HTML + CSS frontend.

Features

• Book Management

  • Add a book with title, author, and publication year
  • View a list of all books currently in the library

• Member Management

  • Register a member with name and member ID
  • View a list of all registered members

• Borrowing Records

  • Record when a member borrows a book (member + book title)
  • View all borrowing records

• Simple Web UI

  • One page (index.html) with three sections: Books, Members, and Borrowing
  • Links to separate pages that list books, members, and borrowing records

Note: All data is stored in memory only. When the server restarts, books, members, and loans are cleared.

Project Structure.

• LibraryServer.java – Java HTTP server, routes and in-memory storage
• index.html – Main UI for managing books, members, and borrowing
• style.css – Styling for the main page and cards

---

Prerequisites

• Java (JDK 8+ recommended)

No external libraries are required; everything uses the standard Java runtime and the built-in HTTP server.

How to Run

1. Compile the Java server:

   javac LibraryServer.java

2. Run the server:

   java LibraryServer

3. You should see in the console:

    Server started at http://localhost:8080
   

4. Open the web UI:

   • Option A (recommended): Open a browser at http://localhost:8080/
   • Option B: Open index.html directly in your browser (forms still post to http://localhost:8080/... so the server must be running).

Limitations and Possible Improvements

• Data is not persisted (in-memory lists only).
• Books, members, and loans are stored as plain strings (no rich data model).
• No authentication or user roles.

Possible improvements:

• Add a Book and Member class with IDs and richer fields.
• Save data to a file or database so it survives restarts.
• Add return dates, due dates, and a "returned" status for loans.
• Add search, edit, and delete operations from the UI.
