Part 5

Modify the Program by adding a button to the GUI that allows the user to move to the first item, the previous item, the next item, and the last item in the data. If the first item is displayed and the user clicks on the Previous button, the last item should display. If the last item is displayed and the user clicks on the Next button, the first item should display.

Part 6

Modify the Program to include an Add button, a Delete button, and a Modify button on the GUI. These buttons should allow the user to perform the corresponding actions on the item name, the number of units in stock, and the price of each unit. An item added to the inventory should have an item number one more than the previous last item.

Add a Save button to the GUI that saves the data to C:\data\[url removed, login to view] file.

Use exception handling to create the directory and file if necessary.

Add a search button to the GUI that allows the user to search for an item in the inventory by the product name. If the product is not found, the GUI should display an appropriate message. If the product is found, the GUI should display that product's information in the GUI.
