Introduction 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 0.5 0. 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 "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: Video If you are not completely comfortable with file I/O, then here is a .
