Overview

Java 5.0, code-named "Tiger", promises to be the most significant new version of Java since the introduction of the language. With over a hundred substantial changes to the core language, as well as numerous library and API additions, developers have a variety of new features, facilities, and techniques available.

But with so many changes, where do you start? You could read through the lengthy, often boring language specification; you could wait for the latest 500 page tome on concepts and theory; you could even play around with the new JDK, hoping you figure things out—or you can get straight to work with Java 5.0 Tiger: A Developer's Notebook.

This no-nonsense, down-and-dirty guide by bestselling Java authors Brett McLaughlin and David Flanagan skips all the boring prose and lecture, and jumps right into Tiger. You'll have a handle on the important new features of the language by the end of the first chapter, and be neck-deep in code before you hit the halfway point. Using the task-oriented format of this new series, you'll get complete practical coverage of generics, learn how boxing and unboxing affects your type conversions, understand the power of varargs, learn how to write enumerated types and annotations, master Java's new formatting methods and the for/in loop, and even get a grip on concurrency in the JVM.

Light on theory and long on practical application, Java 5.0 Tiger: A Developer's Notebook allows you to cut to the chase, getting straight to work with Tiger's new features. The new Developer's Notebooks series from O'Reilly covers important new tools for software developers. Emphasizing example over explanation and practice over theory, they focus on learning by doing—you'll get the goods straight from the masters, in an informal and code-intensive style that suits developers. If you've been curious about Tiger, but haven't known where to start, this no-fluff, lab-style guide is the solution.

Meet the Author

Brett McLaughlin is a bestselling and award-winning non-fiction author. His books on computer programming, home theater, and analysis and design have sold in excess of 100,000 copies. He has been writing, editing, and producing technical books for nearly a decade, and is as comfortable in front of a word processor as he is behind a guitar, chasing his two sons and his daughter around the house, or laughing at reruns of Arrested Development with his wife.

Brett spends most of his time these days on cognitive theory, codifying and expanding on the learning principles that shaped the Head First series into a bestselling phenomenon. He's curious about how humans best learn, why Star Wars was so formulaic and still so successful, and is adamant that a good video game is the most effective learning paradigm we have.

    Quick learning about 1.5

    Java 1.5 has started to emerge into general usage. But most of us Java programmers are still safely ensconced in 1.4. Not a few are undoubtedly wondering what the big deal is about 1.5. If you're like me, you are probably quite satisfied with 1.4. Well this book quickly attempts to change that opinion. It hits all the new stuff, with simple descriptions and example code. Like autoboxing. Nothing deep about this, to say the least. But it really eliminates a lot of visual clutter in your source code, when you have to go between a primitive and its wrapper type. It is the analog of how you can do (eg) System.out.println(' t='+t+' d='+d); where t and d can be any primitive types, and the jvm figures out the printing for you. You don't have to specifically describe the output format for each type, as you have to in C. The wonder about autoboxing (and its inverse) is that it was not introduced way earlier. Well, anyway, you have it now. Long time C programmers will also welcome varargs, which are variable argument lists. Ever since Java came out in 1996, many asked for this ability. This push has gone on for years. Finally, they scored and we have varargs. Other 1.5 changes are covered. But the above should be enough to give you a flavour of what the book offers.
