In this excercise, you will design and implement a library management system. The library management system will be for an engineering school that has the following departments: Computer Engineering (CPEN), Electrical Engineering (ELEN), Industrial Engineering (IMEN), Mechanical Engineering (MEEN) and Civil Engineering (CIEN). The system will have the following requirements:

Each book has a title, author, ISBN number, number of pages, edition, publisher and engineering type (CPEN, ELEN, IMEN, MEEN or CIEN)

There are faculty accounts that have first name, last name, department, ID and position (adjunct professor, assistant professor, professor) and amount of borrowed books

There are student accounts that have first name, last name, ID, department and level (1, 2, 3 or 4) and amount of borrowed books

The library management system keeps track of books, and users by using files.

One file handles book information

One file handles user information

One file registers a name and a borrowed book.

There is a Registry class that holds a borrowers ID and the ISBN number of the borrowed book.

Students of levels 1 and 2 can only borrow up to 3 books, students of levels 3 and 4 can borrow up to 5 books. Faculty can borrow up to 6 books.

When returning a book, you should input the amount of days the user held the book. The first 15 days are free, while extra days have a cost of $5.

The interface that you should use for this program is:

package projectinterface;

public interface LibraryInterface { public void addBook(Book book); public void addStudent(Student student); public void addFaculty(Faculty faculty); public void printBookInfo(String ISBN); public void deleteBook(String ISBN); public void deleteStudent(String ID); public void deleteFaculty(String ID); public boolean checkBookIsBorrowed(String ISBN); public boolean checkStudentHasBooks(String ID); public boolean checkFacultyHasBooks(String ID); public void printAllBooks(); public void printAllBooksForPerson(String ID); public void printAllBooksByDepartment(String department); public void borrowBookToStudent(String ID, String ISBN); public void borrowBookToFaculty(String ID, String ISBN); public void returnBookFromStudent(String ID, String ISBN); public void returnBookFromFaculty(String ID, String ISBN); public void printBorrowedBookRegistry(); }

The program should have a menu that allows the following:

Add a new book

Add a new student

Add a Faculty

Search for information about a specific book (use ISBN)

Delete a book (use ISBN)

Check first if a user hasnt borrowed the book

Delete a user from the system

Verify the user has returned all his books first

Show all books

Show all books for a specific user (use ID)

Show all books for a specific department

Borrow a book to a user

Return a book

Show every user and the books borrowed by user

Design constraints:

Inheritance: Student and Faculty classes extend the Person class.

Composition: Library class has:

ArrayList

ArrayList

ArrayList

ArrayList

Interface: Library implements the provided LibraryInterface class.
