Designing and implementing a simple Library Management System $($LMS$)$ for a small

library. The goal of this assignment is for you to practice designing a system using

Object$-$Oriented Programming $($OOP$)$ principles, create the necessary UML diagrams,

and implement the system in Java.

General Requirements

You should implement inheritance, encapsulation, abstraction or polymorphism to

store the necessary information. There is no need to implement any database.

However, it will be an advantage to those who are able to connect the system to a

database

You are advised to conduct some research and understand the concepts and

implementation of composition as well as the necessary UML diagram such as Class

diagram.

System Requirements

$1.$ Manage Library Books

The system must allow the librarian to:

$$ Add new books: Each book should have attributes such as title, author,

ISBN number, and availability status $($whether the book is currently

available for borrowing or not$).$

$$ Update book information: The librarian should be able to modify the

details of existing books.

$$ Delete a book: The system should allow the deletion of a book from the

catalog.

$$ Search for books: The librarian should be able to search for books by

title, author, or ISBN number.

$2.$ Borrowing and Returning Books

The system must support:

$$ Borrowing books: Members should be able to borrow books from the

library. The system should check if the book is available and update the

availability status accordingly.

$$ Returning books: Members should be able to return books. The system

should update the availability status of the returned books.

$$ Transaction recording: The system should keep track of all borrowing

transactions, including which member borrowed which book and when

it was borrowed and returned.
