The Essential Java Class Reference is a hands-on introduction to powerful Java programming resources available from Sun Microsystems. This accessible reference to the key class libraries used for everyday programming is superb as a stand-alone guide for beginning or intermediate Java programmers or can be used to supplement Java programming books. The book contains descriptions of the 125 most-used Java classes, with approximately 100 short code examples and five complete programs.
Features/BenefitsThis manual has been written to meet demand for an easy-to-use guide to the rich resources available from Sun Microsystems to support the Java programming language. The manual can be used as a stand-alone guide or in conjunction with introductory and intermediate Java textbooks.
The programming tools presented in this manual are very powerful, but often not easily accessible to beginning programmers. In addition, descriptions of how to use these tools cannot easily be integrated into introductory textbooks. The manual is a perfect supplement to programming textbooks that must focus on the Java language and its features. Here, the focus is a hands-on and tutorial-style introduction to programming tools and resources.
Let's now take a look at the tools and resources covered in this manual.
One of the great features of the Java programming language is that it is freely available. The first section in this book is a brief introduction to two free Java tools (or sets of tools, really): the Java SDK and the Community Edition of Forte for Java. Those two sets of tools are included on the CD that accompanies the book.
Another great feature of Java is the Java API, which is a large library of classes that you can use in your programs. The classes in the API are useful because they make lots of things easier, including graphics and network communication, but there are many classes, with many methods, that can be confusing to beginning and intermediate Java programmers. The Java Class Reference will help you find your way around the Java API. In the class reference, you'll find descriptions of the most commonly used classes and methods. In fact, the classes and methods presented were chosen by Prentice Hall textbook authors specifically because they will be most useful to the beginning and intermediate Java programmer.
Even the best description can leave you wondering how to use a method in your program, so the class reference also includes plenty of code examples, ranging from a single line of code to 10 or 20 lines. If you want to write a Java program and don't know where to start, turn to the "Complete Examples" chapter of this book. That chapter includes examples of both applications and applets. There is a GUI (Graphic User Interface) application and a text-interface application, so whatever kind of Java program you're writing, you'll find a starting point in this section. You can copy and paste these programs in from the examples contained on the accompanying CD, compile them, and run them to get a feel for what they do. Then add your own code and classes to get the program you want.
If you like to show off your programs, you can put them on a Web site. Anyone in the world who has an Internet connection and a Java-enabled browser can try your programs out. Of course, a great applet deserves a great Web page, and the HTML Tutorial section will teach you how to put a Web page together and add your applet.
If you're new to programming, you've probably heard a lot of terms that aren't familiar or heard familiar words used in unfamiliar ways. The "Java Programming Glossary" can help you figure out just what people are talking about when they mention "objects", "references", or any number of things. If you have some programming experience, but are new to Java, the glossary will help you learn terms that you might not be familiar with, like "exception" or "final."
Unfortunately, compilers are notorious for giving error messages that make no sense. Eventually you'll figure them all out, but until then you'll want to turn to the "Java Error Messages with Explanations" section of the book. There you'll find descriptions of errors that are more than one line long, as well as likely causes of the error. ACKNOWLEDGEMENTS
Of course, this reference manual wouldn't be possible without the Java language and documentation produced by Sun Microsystems. Sun's API description is the definitive documentation for Java classes and so was an important source of information for the "Java Class Reference" section.
I would like to thank everyone who contributed to this manual, including textbook authors and reviewers. Several people contributed to the list of classes to be included, and I appreciate their help in the difficult job of deciding which classes to include.
I particularly want to thank Jake Warde for giving me the opportunity to write the manual and for a great deal of help. I also appreciate the help of the people at Prentice Hall who made this project possible and contributed in many ways.
Finally, I want to thank my great family: my wife, Kristy, and our children, Jessica, Alex, and Jason. Nothing I do would be as good if they weren't part of my life.
