(Fuzzy Dice Order Form Application) Write an application that allows users to pro- cess orders for fuzzy dice as shown in Fig. 7.30. The application should calculate the total price of the order, including tax. JTextFields for inputting the order number, the customer name and the shipping address are provided. Initially, these fields contain text that describes their purpose. If the user does not modify this text, a message dialog is displayed. Provide JCheckBoxes for selecting the fuzzy-dice color and JTextFields for inputting the quantities of fuzzy dice to order. If the user does not select any of the fuzzy-dice JCheckBoxes, a mes- sage dialog is displayed. The application should also contain a JButton that, when clicked, calculates the subtotals for each typ

a) Copying the template to your working directory. Copy the C:Examples Tutorial07ExercisesFuzzyDiceOrderForm directory to your C:SimplyJava directory.
b) Opening the template file. Open the FuzzyDiceOrderForm.java file in your text editor.
c) Customizing the JCheckBoxes. In line 137 set the bounds (10, 227, 93, 21) and text
(White/Black) properties of whiteTypeJCheckBox. In line 143 set the bounds (10,
252, 88, 21) and text (Red/Black) properties of redTypeJCheckBox.
d) Coding the calculateJButtonActionPerformed method. Code should be placed in the calculateJButtonActionPerformed method, which begins in line 283. In line
298, replace the keyword true with an expression that will return true if white- TypeJCheckBox has been selected. On line 305 replace keyword true with an expres- sion that will return true if redTypeJCheckBox has been selected. These if statements should now calculate subtotals for each type of dice if that type of dice has been
