Create a Java program for managing a book store's inventory system. The inventory information is stored in a text file named "book_inventory.txt." Each line in the file represents a book with the following format: "BookID, Title, Quantity, Price." The program should allow the user to add new books, update the quantity of existing books, and display the total value of the inventory. Ensure that the program checks for the existence of "book_inventory.txt" and handles cases where the file is empty. Utilize functions to organize your code effectively, with comments explaining each function's purpose. You can use data structures like HashMap or ArrayList to store and manipulate inventory data. The program should output the updated inventory information to a file named "updated_book_inventory.txt." Ex: book_inventory.txt: 201, Java Programming, 20, 45.99 202, Algorithms Unlocked, 15, 30.50 203, Data Structures and Algorithms, 25, 55.99 (updated_book_inventory.txt after adding 10 Python Basics books and updating Java Programming quantity to 25) 201, Java Programming, 25, 45.99 202, Algorithms Unlocked, 15, 30.50 203, Data Structures and Algorithms, 25, 55.99 204, Python Basics, 10, 39.99.

Transcribed Image Text:Create a Java program for managing a book store's inventory system. The inventory
information is stored in a text file named "book_inventory.txt."
Each line in the file represents a book with the following format: "BookID, Title,
Quantity, Price."
The program should allow the user to add new books, update the quantity of existing
books, and display the total value of the inventory.
Ensure that the program checks for the existence of "book_inventory.txt" and handles
cases where the file is empty.
Utilize functions to organize your code effectively, with comments explaining each
function's purpose.
You can use data structures like HashMap or ArrayList to store and manipulate
inventory data.
The program should output the updated inventory information to a file named
"updated_book_inventory.txt."
Ex:
book_inventory.txt:
201, Java Programming, 20, 45.99
202, Algorithms Unlocked, 15, 30.50
203, Data Structures and Algorithms, 25, 55.99
(updated_book_inventory.txt after adding 10 Python Basics books and updating Java
Programming quantity to 25)
201, Java Programming, 25, 45.99
202, Algorithms Unlocked, 15, 30.50
203, Data Structures and Algorithms, 25, 55.99
