This book is written for students who are currently taking a Java course that uses Sun ONE Studio and for Java programmers who want to develop Java projects using Sun ONE Studio.

You can use Java 2 SDK to write Java programs. Java 2 SDK (formerly known as JDK) consists of a set of separate programs, such as compiler and interpreter, each of which is invoked from a command line. Besides Java 2 SDK, there are more than a dozen Java development tools on the market today, including Sun ONE Studio (formerly known as Forte for Java), Borland JBuilder, IBM Visual Age for Java, and WebGain Visual Cafe. These tools support an integrated development environment (IDE) for rapidly developing Java programs. Editing, compiling, building, debugging, and online help are integrated in one graphical user interface. Using these tools effectively will greatly increase your programming productivity.

This book introduces Sun ONE Studio. Sun ONE Studio is available in three editions: Community Edition, Enterprise Edition, and Mobile Edition.

• Community Edition is ideal for beginners who wish to learn the basics of Java programming. It can be downloaded free for educational use from wwws.sun.com/software/sundev/jde/index.html.
• Enterprise Edition contains all the components in Community Edition, plus some advanced features for building enterprise applications using J2EE.
• Mobile Edition is for developing applications for mobile devices.

Note: Sun ONE Studio was formerly known as Forte. Forte is still used as a short name for Sun ONE Studio. This book will use Sun ONE Studio and Forte interchangeably.

Note: Sun ONE Studio can run on any platform with a Java Virtual Machine. The screen shots in the tutorial are taken from Windows using Sun ONE Studio 4 Update 1.
