Summary
During this hour, you were introduced to the concept of programming a computer—giving it a set of instructions that tell it what to do. You also might have downloaded and installed a Java development tool that will be used as you write sample programs throughout the book.
If you are still confused about programs, programming languages, or Java in general, that's understandable at this point. Everything will make more sense to you in the next hour, “Writing Your First Program,” which takes a slow trip through the process of creating a Java program.
