Extend and complete program FastFood.java used in the class as follows:

Add two more item lists to the right of the two existing item lists. The first contains a list of fruits with these items and their prices, Apple (89 cents), Orange (79 cents), Peach (99 cents), and Banana (59 cents). The second is a list of beverages with these items and their prices, Soda (85 cents), Coffee (95 cents), Juice (75 cents), and Water (55 cents). Display the first list with a label Fruit Items above it and a button Get Fruit Item below it. Display the second list with a label Beverage Items above it and a button Get Beverage Item below it. The new lists and buttons should appear and work in the same way as the ones currently in the program.

The button to delete an ordered item does not work currently. Extend the program so that an ordered item can be removed either by double-clicking the item or by first selecting the item with a single mouse click and then pressing the delete button. In either case, the price of the item removed should be deducted from the running total. If no selection is made first, the delete button should do nothing.

Add a Clear All button next and to the right of the item delete button and program the button to remove all the items in the ordered list and reset the running total to zero when the button is clicked.
