Transcribed Image Text:Create a Java program for managing a grocery store's inventory system. The
inventory information is stored in a text file named "grocery_inventory.txt."
Each line in the file represents a grocery item with the following format: "ItemID,
ItemName, Quantity, PricePerUnit."
The program should allow the user to add new items, update the quantity of existing
items, and display the total value of the inventory.
Ensure that the program checks for the existence of "grocery_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_grocery_inventory.txt."
Ex:
grocery_inventory.txt:
301, Apples, 50, 1.99
302, Bread, 40, 2.50
303, Milk, 30, 3.99
(updated_grocery_inventory.txt after adding 20 units of Eggs and updating the
quantity of Apples to 60)
301, Apples, 60, 1.99
302, Bread, 40, 2.50
303, Milk, 30, 3.99
304, Eggs, 20, 2.25.
