## Smart Library Management System
- **Project Type**: Object-Oriented Programming with Java (Course BCS306A).
- **Purpose**: To automate physical library core functions including borrowing, returning, and inventory tracking.

## Problem Statement
- Manual record-keeping in ledger books is prone to errors and physical damage.
- Lack of real-time availability checking and difficulty tracking overdue books.

## Objectives & Scope
- Implement OOP concepts: Inheritance (User types) and Encapsulation (Book details).
- Automate fine calculation and ensure persistent storage via File I/O.
- **Modules**: Admin Module (CRUD operations) and Student Module (Search/Borrow/Return).

## Technologies Used
- **Language**: Java JDK 17/21.
- **Tools**: Eclipse, NetBeans, or IntelliJ IDEA.
- **Storage**: CSV File Handling or SQL connectors.
- **Libraries**: Collections Framework (ArrayList, HashMap), Exception Handling, and Streams.

## System Architecture & Logic
- Modular approach where `Main` invokes `LibraryManager`.
- Data is serialized and stored in local files.
- **Core Class Code Sample**: Demonstrates state management for issuing books and polymorphism for User types.

## Efficiency Results
- Digital implementation reduced search and book issue times by over 90%.
- Improved data accuracy and reduced operational friction compared to manual ledger methods.
