Chapter 15.3, Problem 15.9CP
Explanation of Solution
Two examples of direct or indirect subclasses of the Labeled class:
The two examples of subclasses under Labeled class are “RadioButton” and “CheckBox” controls.
RadioButton controls:
- Generally “RadioButton” look in groups of two or more options.
- The controls “RadioButton” is used to permit the user to choose one option from the several possible options.
- It may be selected or deselected.
- The controls “RadioButton” is used to permit the user to choose one option from the several possible options.
- Each “RadioButton” consist of a small circle.
- If a circle appears filled-in, then the “RadioButton” is selected...

The intent of the factory method pattern is to allow a class to differ .. to subclasses
Select one:
a. instantiation
b. abstraction
c. delegation
Subclasses of abstract classes must implement the parent class's abstract methods. You think?
When inheriting from an abstract class, a subclass is obligated to implement each and every one of the abstract methods that the parent class provides. Is there a mistake in my understanding of this?
