Beginning Programming with Java For Dummies

Introduction

What's your story?

Are you a working stiff, interested in knowing more about the way your company's computers work?
Are you a student who needs some extra reading in order to survive a beginning computer course?
Are you a typical computer user - you've 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.
About This Book

The book uses Java - a powerful, general-purpose computer programming language. But Java's subtleties and eccentricities aren't the book's 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 aren't written for real people. Those books don't 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 head. 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.
How to Use This Book

I wish I could say, "Open to a random page of this book and start writing Java code. Just fill in the blanks and don't look back." In a sense, this is true. You can't break anything by writing Java code, so you're always free to experiment.

But I have to be honest: If you don't understand the bigger picture, writing a program is difficult. That's true with any computer programming language - not just Java. If you're typing code without knowing what it's about, and the code doesn't do exactly what you want it to do, you're just plain stuck.

In this book, I divide programming into manageable chunks. Each chunk is (more or less) a chapter. You can jump in anywhere you want - Chapter 5 , Chapter 10 , or wherever. You can even start by poking around in the middle of a chapter. I've tried to make the examples interesting without making one chapter depend on another. When I use an important idea from another chapter, I include a note to help you find your way around.

In general, my advice is as follows:

If you already know something, don't bother reading about it.
If you're curious, don't be afraid to skip ahead. You can always sneak a peek at an earlier chapter, if you really need to do so. Conventions Used in This Book

Almost every technical book starts with a little typeface legend, and Beginning Programming with Java For Dummies, 5th Edition, is no exception. What follows is a brief explanation of the typefaces used in this book:

New terms are set in italics.
When I want you to type something short or perform a step, I use bold.
You'll also see this computerese font. I use the computerese font for Java code, filenames, web page addresses (URLs), onscreen messages, and other such things. Also, if something you need to type is really long, it appears in computerese font on its own line (or lines).
You need to change certain things when you type them on your own computer keyboard. For example, I may ask you to type
