Whats your story?

• Are you a working stiff, interested in knowing more about the way your companys computers work?
• Are you a student who needs to complete some extra reading in order to survive a beginning computer course?
• Are you a typical computer user youve done lots of word processing and you want to do something more interesting with your computer?
• Are you a job seeker with an interest in entering the fast-paced, glamorous, high-profile world of computer programming (or, at least, the decent-paying world of computer programming)?

Well, if you want to write computer programs, this book is for you. This book avoids the snobby of-course-you-already-know assumptions and describes computer programming from scratch.

The book uses Java a powerful, general-purpose computer programming language. But Javas subtleties and eccentricities arent the books main focus. Instead, this book emphasizes a process the process of creating instructions for a computer to follow. Many highfalutin books describe the mechanics of this process the rules, the conventions, and the formalisms. But those other books arent written for real people. Those books dont take you from where you are to where you want to be.

In this book, I assume very little about your experience with computers. As you read each section, you get to see inside my mind. You see the problems that I face, the things that I think, and the solutions that I find. Some problems are the kind that I remember facing when I was a novice; other problems are the kind that I face as an expert. I help you understand, I help you visualize, and I help you create solutions on your own. I even get to tell a few funny stories.

In this book, I make a few assumptions about you, the reader. If one of these assumptions is incorrect, youre probably okay. If all these assumptions are incorrect well, buy the book anyway.

• I assume that you have access to a computer. Heres good news. You can run the code in this book on almost any computer. The only computers you cant use to run this code are ancient things that are more than eight years old (give or take a few years). You can run the latest version of Java on Windows, Macintosh, and Linux computers.

• I assume that you can navigate your computers common menus and dialog boxes. You dont have to be a Windows, Linux, or Macintosh power user, but you should be able to start a program, find a file, put a file into a certain directory that sort of thing. Most of the time, when you practice the stuff in this book, youre typing code on your keyboard, not pointing and clicking the mouse.

  On those rare occasions when you need to drag and drop, cut and paste, or plug and play, I guide you carefully through the steps. But your computer may be configured in any of several billion ways, and my instructions may not quite fit your special situation. So, when you reach one of these platform-specific tasks, try following the steps in this book. If the steps dont quite fit, send me an email message or consult a book with instructions tailored to your system.
