Implement a TestBookInventory driver class as follows:

$2.$ create a global instance of type BookInventory,

$3.$ In the main method, provide a menu$-$driven interface for users to interact with the

inventory system. Each menu option would trigger a method in the BookInventory class.

See sample output for menu options and a logical execution of your program.

$4.$ 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.

$5.$ Ensure that the program gracefully handles file related exceptions $($FileNotFound$,$ I$/$O

exception, etc.$)$ and invalid user inputs.

$6.$ Implement validation checks for user inputs $($e$.$g$.,$ ensure price and quantity are positive

numbers$).$

$7.$ You should handle cases such as duplicate book entries or attempting to delete a non$-$

existent book.

$8.$ Make sure the search functionality allows for case$-$insensitive searches.

$9.$ Test your program thoroughly to ensure all functionalities work as expected.
