Ice Cream Order
Create a JavaFX GUI application named IceCreamOrder that helps you to determine the cost of one ice cream order. The application should have the following appearance when first started (note that chocolate is selected by default):
The above GUI is a scene that holds an HBox, and the HBox in turn holds three TitledPane objects (with the titles "Flavors", "Toppings", and "Order").
The user can select flavor and any number of extras. When they press the Calculate Cost button, then a dialog box with the following style of content it presented to the user:
All ice cream flavors are $2.25. Each extra is 0.50. So, the in the example above, the cone is 2.25, nuts are 0.50 and cherries are 0.50, for a total of 3.25. The Michigan 6% tax is added on for a total of 3.45.
One specific order can be saved at any time. When an order is saved, the information stored on the disk is the flavor and the extras. The file should be named icecream.txt, and the file will always have exactly three lines of text, of the general format:
Flavor Nuts Status Cherries Status
The first line is either "Vanilla", "Chocolate" or "Strawberry".
The second line is always "With_Nuts" or "Without_Nuts".
The third line is always "With_Cherries" or "Without_Cherries".
So, for example, a saved order might look like:
Chocolate Without_Nuts With_Cherries
At any point in time the user can press the Restore button, and the last saved order will be displayed on the user interface. If there is no file available (nothing has been saved yet) and the user presses Restore, then have the following Alert ERROR message shown to the user:
GUI has three radio buttons, two checkboxes, and a three buttons as shown on the requirements page. The components are grouped in an HBox of three TitledPane containers, and the TitledPanes have titles of "Flavor", "Toppings" and "Order". Clicking the Calculate button calls an event handler that displays a dialog box. The calculations are correct for all combinations of extras. The Michigan tax is calculated correctly. Saves an order to file. If no file exists, then gives an appropriate error message to the user via an Alert. All components look professional and are nicely formatted, such as monetary values are all shown will two digits after the decimal point. |
