Explain the difference between method overloading and method overriding.
What will be an ideal response?
Overriding refers to redefining a method definition in a derived class. When a method
definition is overridden, the new method definition has the exact same number and types of
parameters. An overloaded method has the same name as another method in the class, but number
and/or type of parameters differ.

(Enhanced Fuzzy Dice Order Form Application) Enhance the Fuzzy Dice Order Form application from Exercise 7.13 so that when a JCheckBox is deselected, its correspond- ing quantity JTextField is made uneditable and the quantity value is reset to 0 (Fig. 7.33). All the monetary values should also be reset to $0.00. When a JCheckBox is selected, its cor- responding quantity JTextField should then be made editable. Again, all the monetary val- ues should be reset to $0.00. To solve this exercise, you will need to use methods for the JCheckBoxes. Empty methods are provided for you. The steps below will walk you through adding the proper code to these methods.
```
a) Copying the template to your working directory. Copy the C:Examples Tutorial07ExercisesFuzzyDiceOrderFormEnhanced directory to your C:Sim- plyJava directory.
b) Opening the template file. Open the FuzzyDiceOrderForm.java file in your text editor.
c) Customizing the application’s components. Set the editable property of whiteQuan- tityJTextField and redQuantityJTextField to false. You want both JText- Fields to be uneditable at the start of the application. On lines 189 and 198, set the editable property of each JTextField to false after the code that sets each JText- Field text property to "0".
d) Coding the whiteTypeJCheckBoxActionPerformed method. In the whiteType- JCheckBoxActionPerformed method (which is right after the calculateJButton- ActionPerformed method), test whether whiteTypeJCheckBox has been selected. If it has, set whiteQuantityJTextField’s editable property to true. If the JCheckBox has not been selected, set whiteQuantityJTextField’s editable prop
