Campus Library Management System (CLMS)

A multithreaded, JavaFX-based library management system designed for a campus environment.
The application manages student records, book catalogs, rentals and returns, and per-student log histories using binary file I/O.
This project demonstrates object-oriented design, binary persistence, thread-safe operations, and a responsive JavaFX interface.

Key Features

Student Record Management

• Add, search, and list students
• Records stored in students.dat using binary serialization
• Uses in-memory indexing for efficient lookups

Book Catalog Management

• Add books and view all books
• Tracks available and checked-out copies
• Persisted to catalog.dat

Rent and Return System

• Students rent books through threaded record matching
• Logs stored per student in logs/<studentId>.dat
• Each log entry includes:
  • timestamp
  • event type (RENT or RETURN)
  • ISBN
  • book title

Multithreading and Synchronization

• Uses ExecutorService for concurrent lookups
• JavaFX Task keeps the UI responsive
• ReentrantReadWriteLock ensures thread-safe file access

JavaFX Interface

• Menu bar: Students, Books, Rentals, Exit
• TabPane containing:
  • Student Records
  • Book Catalog
  • Student Logs
• Split pane: Students on the left, logs on the right
• UI updates automatically after rent/return actions
