Question

Develop an application using a JTabbedPane to order a pizza. You will need to ask the customer for their name and phone number. You will ask for the size (choose one) and toppings (choose many) and compute the total. After computing the total, provide a button to display the order summary, which includes the name, phone number, size, toppings, and total. The prices are listed below. Screenshots of a possible solution are included. Your application must include four tabs and open a new window when the button is clicked.Small: 8.00Medium: 10.00Large: 12.00Each topping is 2.00 extra.
