IN JAVA PLEASE COMPLETE ALL CLASSES AND METHODS INCLUDING MAIN

Objective: Design and implement a Java program for managing a book inventory system for a

popular bookstore chain. The program should allow users to perform various operations such as

adding books, deleting books, updating book information, searching for books, and displaying

the entire inventory. There should also be a method to calculate the total value of the collection

for inventory taxes. All book information should be stored in a file and loaded into an array when

the program starts. Changes made during the program's execution should be reflected in the file

by writing back changes to the file.

Requirements:

$1.$ Create a Book class with the following attributes:

o title

o ISBN $($unique for each book$)$

o Author

o yearOfPublication

o retailPrice

o quantityOnHand

o Methods

$1.$ constructors

$2.$ Accessors

$3.$ Mutators

$4.$ toString

$2.$ Create an Author class with the following attributes

o name

o birthYear

o nationality

o Methods

$1.$ constructors

$2.$ Accessors

$3.$ Mutators

$4.$ toString

$5..$equals

$1.$ Two authors are equal if their name and birth year are equal

$3.$ Implement a BookInventory class to manage the book inventory system. This class

should include methods for:

o Reading the book inventory from a file into a single$-$dimensional array.

o Writing the current book inventory back to the file, replacing the original content.

o Adding a new book to the inventory.

o Deleting a book from the inventory.

o Updating book information.

o Searching for a book by title, Author, or ISBN.

$1.$ Overload three search methods

o Displaying the entire inventory.

o Changing the price of all books by a fixed percentage $($during sales$)$

o Calculating the retail value of the entire inventory

$4.$ Ensure that the program gracefully handles file I$/$O exceptions and invalid user inputs.

Instructions:

$1.$ Start by creating the Book and Author classes with appropriate attributes, constructors,

accessor and mutator methods.

$2.$ Implement the BookInventory class with the required methods.

$3.$ Write a main method to create an instance of the BookInventory class and provide a

menu$-$driven interface for users to interact with the inventory system.

$4.$ Use file I$/$O operations to read the initial inventory from a file when the program starts

and save any changes back to the file before exiting.

$5.$ Implement validation checks for user inputs $($e$.$g$.,$ ensure price and quantity are positive

numbers$).$

$6.$ You should implement error handling for cases such as duplicate book entries or

attempting to delete a non$-$existent book.

$7.$ Make sure the search functionality allows for case$-$insensitive searches.

$8.$ Test your program thoroughly to ensure all functionalities work as expected.

Note: Feel free to reach out if you need further clarification or assistance with any aspect of the

assignment.

Design Requirements:

$$ Create a class diagram for two classes$-$ Book and Author, and pseudocode for

BookInventory

$$ The classes should be placed in a package with the name edu.ilstu
