Many serious Java programmers, especially enterprise Java programmers, consider the new I/O API--called NIO for New Input/Output--the most important feature in the 1.4 version of the Java 2 Standard Edition. The NIO package includes many things that have been missing from previous editions of Java that are critical to writing high-performance, large-scale applications: improvements in the areas of buffer management, scalable network and file I/O, character-set support, and regular expression matching. Most of all, it boosts performance and speed dramatically. Java NIO explores the new I/O capabilities of version 1.4 in detail and shows you how to put these features to work to greatly improve the efficiency of the Java code you write. This compact volume examines the typical challenges that Java programmers face with I/O and shows you how to take advantage of the capabilities of the new I/O features. You?ll learn how to put these tools to work using examples of common, real-world I/O problems and see how the new features have a direct impact on responsiveness, scalability, and reliability. The book includes: * A rundown of the new features in NIO * Basic and advanced I/O Concepts * Binary I/O and the new buffer classes * Memory mapped files and file locking * Character I/O: encoding, decoding and transforming character data * Regular Expressions and the new java.util.regex package * Muliplexing with java.nio Because the NIO APIs supplement the I/O features of version 1.3, rather than replace them, you'll also learn when to use new APIs and when the older 1.3 I/O APIs are better suited to your particular application. Java NIO is for any Java programmer who is interested in learning how to boost I/O performance, but if you're developing applications where performance is critical, such as game computing or large-scale enterprise applications, you'll want to give this book a permanent spot on your bookshelf. With the NIO APIs, Java no longer takes a backseat to any language when it comes to performance. Java NIO will help you realize the benefits of these exciting new features.
我认为是 java 从业者必读的一本书。中英文版在网络上都可以下载到。推荐朋友们读一读。作者写的也是十分的简明易懂。在工作中和找工作的时候,这本书中的内容一定会用到的。 注: 我没什么可以写的了。还写什么啊。
評分这本书是介绍java nio的基础书籍,原理讲的还是挺明白的,比较好懂,就是例子比较少。nio对于java程序员来说可能不是很好理解,但是对于C程序员来说,就是epoll的一个封装。 我本人是C程序员,对java比较感兴趣,发现java nio里面很多的东西都是对C原生api的封装,如epoll, mma...

評分要是想学习 java nio ,以及 nio 的扩展 netty 会是个不错的选择 sun 本身的实现 不足参考 因为没文档和源码 还有的话 阅读 netty 之前 java 并发编程 java 网络编程 或者 tcp/ip 心里要有个 B数啊 不然 socket 看起来类

好吧,我讀的是中文版的,感覺各種羅嗦,加上滿篇的貼代碼,,,
评分媽蛋,講啥瞭?
评分學習瞭NIO的緩衝區、通道與選擇器,但有沒有更深入一些的書籍呀
评分對NIO的基本概念和特性進行瞭總體的介紹,是NIO入門學習的首選。
评分前麵幾章很不錯。
