Question

Design and implement a Java program that creates a GUI that will allow a customer to order pizza and other items from a Pizza Paarlor. The customer should be able to order a variety of items which are listed below. The GUI should allow the customer (viaJavaFX UI Controls - text areas, buttons, checkbox, radio button, etc.) to input the following information:

Name of the customer First Name Last Name

Phone number of the customer

Type of food being order options are:

pizza calzone garlic knots baked ziti antipasto

Quantity of each food item being ordered

Additional information

Pizza size Small round Large round Sicilian Pizza toppings Pepperoni Sausage Meatballs Mushrooms Onions Peppers Extra cheese

Address for delivery Street Number Street Name Conditions: Small pies can have no more than 4 toppings. Large pies can have as many toppings as the customer would like. Sicilian pies can have no toppings.

The customer must specify the quantity of each item they have chosen.

The number of each item ordered cannot exceed 50.

The GUI will have two buttons. The first will be used to create a running total of the current order.

This button should be clicked every time an item is added to the order to give a running total of the current order.

The second button will be used to display the following:

Name of customer Phone Number of customer All items and quantity ordered

The grand total for the order Pricing Base Price for items : Small Plain Pie – $11.25 Large Plain Pie – $14.00 Sicilian Pie – $18.50 Calzone - $7.75 Garlic Knots -$3.50 Baked Ziti - $11.00 AntiPasto - $12.50 Additional fees for Toppings: Small Pie - $2.00 per topping Large Pie - $3.00 per topping Once calculated the system should display the Name and Phone Number of the customer, Address for delivery, items ordered and quantity for each and the cost of the entire purchase. Error checking of all data is required.
