Version 5.0 of the Java 2 Standard Edition SDK is the most important upgrade since Java first appeared a decade ago. With Java 5.0, you’ll not only find substantial changes in the platform, but to the language itself-something that developers of Java took five years to complete. The main goal of Java 5.0 is to make it easier for you to develop safe, powerful code, but none of these improvements makes Java any easier to learn, even if you’ve programmed with Java for years. And that means our bestselling hands-on tutorial takes on even greater significance.

Learning Java is the most widely sought introduction to the programming language that’s changed the way we think about computing. Our updated third edition takes an objective, no-nonsense approach to the new features in Java 5.0, some of which are drastically different from the way things were done in any previous versions. The most essential change is the addition of “generics”, a feature that allows developers to write, test, and deploy code once, and then reuse the code again and again for different data types. The beauty of generics is that more problems will be caught during development, and Learning Java will show you exactly how it’s done.

Java 5.0 also adds more than 1,000 new classes to the Java library. That means 1,000 new things you can do without having to program it in yourself. That’s a huge change. With our book’s practical examples, you’ll come up to speed quickly on this and other new features such as loops and threads. The new edition also includes an introduction to Eclipse, the open source IDE that is growing in popularity.

Learning Java, 3rd Edition addresses all of the important uses of Java, such as web applications, servlets, and XML that are increasingly driving enterprise applications. The accompanying CD includes the Java 5.0 SDK for Windows, Linux, and Solaris, plus the Eclipse IDE, the NetBeans IDE, and the many example programs from the book.

How many times have you reached an impasse while writing code because you couldn’t remember how something in Java worked? This new pocket guide is designed to keep you moving. Concise, convenient and easy to use, the Java Pocket Guide gives you Java stripped down to its bare essentials — in fact, it’s the only book on Java that you can actually fit in your pocket.

Written by Robert and Patricia Liguori, senior software and lead information engineers for Java-based air traffic management and simulation environments, Java Pocket Guide contains everything you really need to know about Java, particularly everything you need to remember. The book pays special attention to the new areas in Java 5 and 6, such as generics and annotations.

Why do you need the Java Pocket Guide?

• It’s the only CliffsNotes-style guide to Java available
• Lets you find important things quickly without consulting 1000-page tutorials
• Includes many command-line options
• Organized for quick and easy use on the job

If you’re looking to learn some aspect of Java, this is not your book. Java Pocket Guide is for the experienced Java programmers among you who need quick reminders to jog your memory on how something in the language works. Simply put, this pocket guide offers practical help for practicing developers.

This comprehensive guide shows you how to master the most important changes to Java since it was first released. Generics and the greatly expanded collection libraries have tremendously increased the power of Java 5 and Java 6. But they have also confused many developers who haven’t known how to take advantage of these new features.

Java Generics and Collections covers everything from the most basic uses of generics to the strangest corner cases. It teaches you everything you need to know about the collections libraries, so you’ll always know which collection is appropriate for any given task, and how to use it.

Topics covered include:

• Fundamentals of generics: type parameters and generic methods
• Other new features: boxing and unboxing, foreach loops, varargs
• Subtyping and wildcards
• Evolution not revolution: generic libraries with legacy clients and generic clients with legacy libraries
• Generics and reflection
• Design patterns for generics
• Sets, Queues, Lists, Maps, and their implementations
• Concurrent programming and thread safety with collections
• Performance implications of different collections

Generics and the new collection libraries they inspired take Java to a new level. If you want to take your software development practice to a new level, this book is essential reading.

“A brilliant exposition of generics. By far the best book on the topic, it provides a crystal clear tutorial that starts with the basics and ends leaving the reader with a deep understanding of both the use and design of generics.”
