Introduction

8.1 Object-Oriented
Programming

Now that you've mastered the basics of procedural-style programming in
Java, you're finally ready to explore what Java was designed for: object-
oriented programming.This chapter introduces the basic terminology that
you should use to talk about objects and shows you how to declare your
own classes to create your own objects.

8.2 Object State and Behavior

Object State: Fields

Object Behavior: Methods

Mutators and Accessors

Objects are entities that contain state and behavior and that can be used
as parts of larger programs.We'll discuss the concepts of abstraction and
encapsulation, which allow you to use objects at a high level without
understanding their inner details. We'll also discuss ideas for designing
new classes of objects and implementing the programs that utilize them.
