Java Code

Write a program in Java (with a graphical user interface) that will allow the user to order a Pizza. For the pizza, it could be selected with a desired size, and toppings. The user should be able to pay the total cost of the ordered pizza, with 7.75% tax added, and receive the change back.

Must have the following toppings available for selection, with $0.25 for each Vegetarian topping and $0.50 for each Meat topping:

Vegetarian:

Baby Portabella Mushrooms
Fresh-Sliced Roma Tomatoes
Fresh-Sliced Onions
Fresh-Sliced Green Peppers
Black Olives
Sweet Pineapple
Banana Peppers
Jalape�o Peppers
Extra Cheese
Meat:

Pepperoni
Sausage
Spicy Italian Sausage
Ham
Hickory-Smoked Bacon
Grilled All-White Chicken
Turkey
Beef
Salami

Must have the following sizes available for selection, with corresponding price:

� Small - $6.50

� Medium - $8.50

� Large - $12.50

� Extra Large - $16.00

Must have a premium option, in which the extra large size and all of the toppings will be selected. If being requested, must have a receipt saved out at an external file, which could then be printed out later. If no size and no toppings were selected, a standard pizza would be ordered, where the size is small, and it contains only Cheese (same price as Extra Cheese).
