The Library Management System is a Java-based application designed to manage library operations, including book management, borrower management, and borrowing records. This project provides a structured approach to handling library data and operations.

• Book Management: Manage book details such as title, author, genre, and availability.
• eBook Management: Handle eBooks with online access links.
• Borrower Management: Manage borrower information, including roles and fine transactions.
• Borrowing Records: Track borrowing and returning of books, with fine calculations for overdue returns.
• User Authentication: Supports login for librarians and borrowers with role-specific functionalities.
• Graphical User Interface: Utilizes JOptionPane for user interaction and management tasks.

• Java: Core programming language used for implementing library operations.
• Vector: Utilized for managing collections of books, borrowers, and borrowing records.
• JOptionPane: Provides a simple GUI for user interaction.

• Book.java: Defines the Book class with attributes and methods for managing book details and borrowing records.
• BookFineTransaction.java: Manages fine transactions with attributes for transaction ID, amount, and payment date.
• BookSearching.java: Provides functionality to search for books by title or ID.
• Borrower.java: Manages borrower details, including borrowing records and fine calculations.
• BorrowingRecord.java: Tracks borrowing and returning of books, including fine calculations for overdue returns.
• Data.java: Handles reading and filtering of user and book data from files.
• Librarian.java: Manages librarian details and operations.
• Library.java: Main program file containing the implementation of library operations and user interaction.
• User.java: Base class for user management, including login functionality.
