Learning Java, 3rd Edition By Jonathan Knudsen, Patrick Niemeyer Publisher: O'Reilly Pub Date: May 2005 ISBN: 0-596-00873-2 Pages: 976 Table of Contents | Index 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 Learning Java, 3rd Edition By Jonathan Knudsen, Patrick Niemeyer Publisher: O'Reilly Pub Date: May 2005 ISBN: 0-596-00873-2 Pages: 976 Table of Contents | Index Copyright Preface New Developments Using This Book Online Resources Conventions Used in This Book Using Code Examples Safari Enabled How to Contact Us Acknowledgments Chapter 1 A Modern Language Section 1.1 Enter Java Section 1.2 A Virtual Machine Section 1.3 Java Compared with Other Languages Section 1.4 Safety of Design Section 1.5 Safety of Implementation Section 1.6 Application and User-Level Security Section 1.7 Java and the Web Section 1.8 Java as a General Application Language Section 1.9 A Java Road Map Chapter 2 A First Application Section 2.1 Java Tools and Environment Section 2.2 HelloJava Section 2.3 HelloJava2: The Sequel Section 2.4 HelloJava3: The Button Strikes!
