CHAPTER 27 — Using Objects and Classes

This chapter reinforces the topics introduced in the last two chapters, and discusses several new topics. The Point class class is used as an example.

Chapter Topics:

• The Point class.
• Class descriptions.
• The toString() method
• Changing the data in an object vs. constructing a new object
• The equals() method.
• The == operator (again).
• Aliases.

You have seen some of the material in this chapter before; however, don't skip it or rush through it. The purpose of this chapter is review and reinforcement of topics that you may still be somewhat unclear about. If you rush through, you will not clarify anything, and may make things less clear.
