The real meat is in Java 5. Generics, Autoboxing, Annotations.

blocks|key|4735381|text|我强烈推荐Brian+Goetz、Tim+Peierls、Joshua+Bloch和Joseph+Bowbeer的Java+Concurrency+in+Practice。它只关注良好的并发编码，但包含了有关Java5和6库中新的并发特性的优秀指南。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4735382|当然，它对其他特性没有任何帮助，但如果您曾经处理过线程(如果您有GUI，那么您就有线程)，那么这本书是必不可少的。|4735383|entityMap|0|LINK|mutability|MUTABLE|url|http://www.amazon.co.uk/Java-Concurrency-Practice-Brian-Goetz/dp/0321349601/ref=sr_1_1?ie=UTF8&s=books&qid=1221490235&sr=8-1^0|1L|S|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

I would thoroughly recommend <a href="http://www.amazon.co.uk/Java-Concurrency-Practice-Brian-Goetz/dp/0321349601/ref=sr_1_1?ie=UTF8&amp;s=books&amp;qid=1221490235&amp;sr=8-1" rel="nofollow noreferrer">Java Concurrency in Practice</a> by Brian Goetz, Tim Peierls, Joshua Bloch, and Joseph Bowbeer. It focusses solely on good concurrency coding, but includes excellent guidance on the new concurrency features in the Java 5 and 6 libraries.

Of course, it is no help at all on the other features, but if you ever deal with threads (and if you have a GUI, then you have threads), then this book is indispensable.

blocks|key|951609|text|Java+5引入了几个主要更新，例如语言改进(即注释、泛型、自动装箱和改进的循环语法)等。注释是一种使用元数据标记类的机制，以便元数据感知程序可以使用它们。泛型是一种为属于集合的对象指定类型的机制，例如Arraylist，以便在编译时保证类型安全。自动装箱允许在原始类型(例如int)和包装器类型(例如Integer)之间进行自动转换。改进的循环语法包括每个循环的增强，以便相对容易地遍历数组或集合的项。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|951610|Java6专注于新的规范和API，包括XML、Web+Services、JDBC4.0版、基于注释的编程、API+for+Java编译器和Application+client+GUI.With新的编译器API随着Java6的添加，Java编译器现在可以接收和/或发送输出到文件系统的抽象(程序可以指定/处理编译器输出)。此外，Java+6在AWT+(更快的闪屏和对系统托盘的支持)和SWING+(更好的拖放、对自定义布局的支持、多线程增强和编写GIF图像的能力)中添加了对应用程序GUI功能的增强。|951611|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Java 5 introduced several major updates, such as language improvements (i.e. Annotations, Generics, Autoboxing, and improved syntax for looping) among many others. Annotation is a mechanism for tagging classes with metadata so that, they can be used by metadata-aware programs. Generics is a mechanism of specifying types for objects belonging to collections, such as Arraylists, so that type safety is guaranteed at compile time. Autoboxing allows the automatic conversions between primitive types (e.g. int) and wrapper types (e.g. Integer). Improved syntax for looping includes the enhancements for each loop for going through the items of array or collections comparatively easily.

Java 6 focuses on new specifications and APIs including XML, Web Services, JDBC version 4.0, programming based on Annotations, API’s for Java compiler and Application client GUI.With new compiler API added with Java 6, the java compiler can now receive and/or send output to an abstraction of the file system (programs can specify/process compiler output). Furthermore, Java 6 added enhancements to the applications GUI capabilities in AWT (faster splash screens and support for system tray) and SWING (better drag-and-drop, support for customizing layouts, multithreading enhancements and ability to write GIF images).

blocks|key|951445|text|我可以推荐Bruce+Eckel的"Thinking+in+Java“第四版。他回顾了一大堆你可以跳过的基本内容，但他对1.5新特性的处理非常彻底，特别是关于泛型的章节。这是一个很好的Java参考资料。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|951446|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I can recommend Bruce Eckel's "Thinking in Java" 4th edition. He goes over a bunch of basic stuff you can skip, but his treatment of new 1.5 features is very thorough, especially the chapter on generics. And it is a good Java reference to own.

blocks|key|1071862|text|Dietel+:+How+to+program+Java|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1071863|这本书是强烈推荐的。什么都教，做得很好。从简单的Hello+World开始，直到您编写自己的基本编译器。还可以处理数据库。做所有的事情，uml，设计。怎么说都不为过。|1071864|它也是一本漂亮的书，我的意思是在设计和颜色上，它不是干的。|1071865|entityMap|0|LINK|mutability|MUTABLE|url|https://rads.stackoverflow.com/amzn/click/com/0132222205^0|0|S|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

<a href="https://rads.stackoverflow.com/amzn/click/com/0132222205" rel="nofollow noreferrer" rel="nofollow noreferrer">Dietel : How to program Java</a>

This book is highly recommended. Teaches everything, does it well. Starts with simple Hello World and ends up in you writing your own BASIC compiler. handles databases as well. Does everything, uml, design. Just can't say enough about it.

And it is also beautiful book, I mean in design and color and it is not dry.

I'm a very experienced Java programmer who has spent my entire time working with Java 1.4 and earlier. Where can I find a quick reference that will give me everything I need to know about the new features in Java5 and later in a quick reference?
