This chapter is from the book


During this hour, you had a chance to create a Java program, send arguments to a program, and make use of existing programs in the Java Class Library.

The next several hours continue to focus on applications as you become more experienced as a Java programmer. Applications are quicker to test because they don’t require you to do any extra work to run them, as you do for the other kinds of programs.

This hour is the first of several that discuss how to make use of objects and their methods in a Java program. You will return to this subject in Hour 10, “Creating Your First Object.”
