Library Management System (Java)

About the Project

This project is a console and gui-based Library Management System developed using Java. The main goal is to manage books and users by using basic data structures and to practice Object-Oriented Programming concepts in a simple and clear way.

What Does the Project Do?

  • Add, delete, and search books
  • Add and manage users
  • Create a waiting list when a book is not available
  • Undo the last operation

All features are designed with a modular class structure and clean code logic.

Used Data Structures

  • Binary Search Tree (BST): Books and users are stored in BSTs to allow fast searching and organized data management.

  • Queue: A queue is used as a waiting list when a book is already borrowed.

  • Stack: A stack is used to store actions that can be undone.

Undo Mechanism

The project includes an Undo mechanism for important operations. Each action is saved as an UndoAction object and pushed into a Stack. When the user selects undo, the last action is reverted safely.

This mechanism helps to:

  • Keep data consistent
  • Reduce user mistakes
  • Simulate undo logic used in real-world applications
