According to the Authors, “This book teaches you all about the Java language and how to use it to create applets and applications. By the time you get through with this book, you’ll know enough about Java to do just about anything, inside an applet or out. This book is intended for people with at least some basic programming background, which includes people with years of programming experience or people with only a small amount of experience. If you understand what variables, loops, and functions are, you’ll be just fine for this book. The sorts of people who might want to read this book include you, if:
- You’re a real whiz at HTML, understand CGI programming (in perl, Apple Script, Visual Basic, or some other popular CGI language) pretty well, and want to move on to the next level in Web page design.
- You had some Basic or Pascal in school and you have a basic grasp of what programming is, but you’ve heard Java is easy to learn, really powerful, and very cool.
- You’ve programmed C and C++ for many years, you’ve heard this Java thing is becoming really popular and you’re wondering what all the fuss is all about.
- You’ve heard that Java is really good for Web-based applets, and you’re curious about how good it is for creating more general applications.
What if you know programming, but you don’t know object-oriented programming? Fear not. This book assumes no background in object-oriented design. If you know object-oriented programming, in fact, the first couple of days will be easy for you.
This book is intended to be read and absorbed over the course of three weeks. During each week, you’ll read seven chapters that present concepts related to the Java language and the creation of applets and applications.
Teach Yourself Java in 21 Days describes Java primarily in its current state—what’s known as the beta API (Application Programming Interface). This is the version of Java that Netscape and other browsers, such as Spyglass’s Mosaic, support. A previous version of Java, the alpha API, was significantly different from the version described in this book, and the two versions are not compatible with each other. There are other books that describe only the alpha API, and there may still be programs and browsers out there that can only run using alpha Java programs.
Teach Yourself Java in 21 Days uses primarily Java beta because that is the version that is most current and is the version that will continue to be used in the future. The alpha API is obsolete and will eventually die out. If you learn Java using beta API, you’ll be much better prepared for any future changes (which will be minor) than if you have to worry about both APIs at once.
Java is still in development. “Beta” means that Java is not complete and that things may change between the time this book is being written and the time you read this. Keep this in mind as you work with Java and with the software you’ll use to create and compile programs. If things aren’t behaving the way you expect, check the Web sites mentioned at the end of this introduction for more information.
Teach Yourself Java in 21 Days covers the Java language and its class libraries in 21 days, organized as three separate weeks. Each week covers a different broad area of developing Java applets and applications.
