This chapter continues the example of the previous chapter.

Chapter Topics:

• Designing a Circle class.
• Constructors of the class.
• The drawing method.
• Data Access methods.
• Drawing random circles

Recall that at the end of the last chapter the paint() method of the applet was starting to get uncomfortably complicated. This is sometimes a sign that a new class is needed to manage some of the complication. It would be nice to have a Circle class to contain the complications of drawing circles.

QUESTION 1:

Objects have both state (data) and behavior (methods.) In general, what state and what behavior should objects of our class Circle have?
