Assignment Statement

For this assignment you will complete a portion of the Pizza order system that you used with Assignment

3, but instead of the supplied console-based interface you will build your own GUI interface using

JavaFX. You will need your Pizza, LineItem and IllegalPizza classes.

You do not need to implement all of the functionality contained in the assignment 3 console interface. You

do not need to save or load a pizza order from a file. You do not need to delete lines from the order or

modify the quantities of line items in the order. Here is what your GUI must do:

The user must be able to configure a pizza, following the same restrictions listed in assignment 3, by

choosing a size, and then the cheese, ham, green pepper and pineapple toppings. The user's choices

must be limited to the legal options given with the assignment.

Display the cost of the pizza configured by the user.

The user must be able to specify a quantity of these pizzas and must be restricted to entering an integer

between 1 and 100, inclusive.

Display the cost of this quantity of the configured pizza.

A button is used to save the current pizza configuration and quantity as a line item which is added to the

order being displayed. Instead of displaying the current order to the console, display it in the same way

in a TextArea control. Every time this button is clicked by the user another line item is added to and

displayed in the order.

As the last line in the displayed order, show the total order cost (without tax!).

Your GUI must be "monkey proof". The user must not be able to configure an illegal pizza or supply an

illegal quantity. The user cannot be allowed to edit displayed costs or the displayed order. As you might

expect, every time the program starts the order will be empty. Your GUI should also remain fairly stable

on re-sizing and its operation should be self-explanatory and user-friendly.

You should consider using a stylesheet (*.css) file as well as an FXML file edited by SceneBuilder, but

this is not mandatory. Keep in mind, however, that a strength of JavaFX is its ability to separate

appearance, layout and functionality into different files.

There is no need for Javadoc commenting and you will likely only need a few comments in your

functional code to explain what it is doing.

Submission and Grading Scheme

Submit all of your *.java files to the onQ dropbox including Pizza.java, LineItem.java, IllegalPizza.java

and Main.java along with your stylesheet file, your *.fxml file and your controller file(s), if you used

them. It would be easier for your grader if you built your project with all of these files in the application

package. If you did not do so or would rather just submit a single file, create a zip file of your project's src

folder containing the folder and package structure that you did use.

Sixteen marks, out of 20, are allotted for the proper operation of your GUI as specified above. Four marks

are for the style, efficiency and documentation of your code.
