CHAPTER 6
Object-Oriented Programming
Objectives
• Learn what an object is and how it relates to a class.
• Learn how to encapsulate and access data inside an object.
• Learn how to partition your programs into “driver” and “driven” classes, to create an object of the
driven class, and to give the driver a reference to that object.
• Learn the differences between an object’s data and data that is local to a method, and learn how to distinguish between those pieces of data when both have the same name.
• Understand implicit initialization (default values) of various kinds of variables.
• Learn how to trace an object-oriented program.

• Learn how to use a UML class diagram.
• Learn how to make a method return a suitable value.
• Learn how values are passed to methods.
• Write methods that get, set, and test the values of an object’s data.
• Optionally learn how to improve the speed and accuracy of a simulation.
