$$This system will streamline daily library operations and provide an

intuitive interface for staff to interact with the system.

Sample GUI:

$$application to interact with the Book and Library Check

out classes from the previous tasks. The GUI should allow users to perform the following actions:

Book Management:

Input fields and buttons to add books.

User Management:

Input fields and buttons to register users.

Transaction Management:

Input fields and buttons for borrowing and returning books.

Messages:

Use message boxes to display success and warning messages.

Show books:

Opens a new window that displays the list of all books in the library.

Each book is shown with its title, author, ISBN, and availability status.

If no books are available, it displays

$"$

No books available."

Show users:

Opens a new window that displays the list of all registered users.

Each user is shown with their user ID

$,$

$$name$,$ and total fines.

If no users are registered, it displays

$"$

No users registered."

Show borrowed books:

This function opens a new window displaying the list of books currently borrowed along with the

names of the users who borrowed them. If no books are borrowed, it displays a message

indicating that no books are currently borrowed.

Report: An accompanying report describing the design choices, any challenges faced, and how they were

addressed.
