App Beans create a new JavaFX project which is a modification of instructions in the k for Exercise 13.6 with two classes TipCalculator (the JavaFX class) and Order he Tip Calculator as follows: ethod art with an Order class with two instance variables, item a string and price a uble, include two constructors, a no-parameter constructor that passes default va mpty String and zero (0) to the second constructor which then calls the set metho Elude gel methods for both instance variables, there is no need for a toString() Em and price; the set method for price validates that price is greater than zero (0 Etantiate ten objects from the Order class in the start() method of the JavaFX Slication from which two Observablelist objects should be instantiated: (a) an servableList of Strings populated from the get method for the "item" field; ar ObservableList of Doubles (use the wrapper class as the sub type to instantiate ulated from the get method for the price field = JavaFX form will consist of (a) a ListView of Strings from the ObservableL ms"; (b) a Slider that represents tip percentage as an int between 15% and w the current value of the "tip percent" slider in a matching Label); (c) a Bu is clicked to calculate the total bill; and (d) a "result Label de an event handler method for the Button that calculates the total bilr ws: the "price" field from the ObservableList that matches the selected it the List View (the user may purchase only one item at a time) times sales 25%) plus the tip which is the matching "price" from the ObservableList ti ntage from the Slider, display with text labels in the result" Label the se ", its matching price, the sales tax, the amount of the tip" and the "tot ination of layout objects, as well as font and color formatting to create a I looking form window documentation using the Javadoc standard and based upon the downlo for the unit work on all projects in teams of two or three, and, if so, all students ubmit the same project to their own dropboxes in Blackboard.
