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.
不太喜欢本书讲解例子的方式, 【2016.8.5 重读,正则 和 字符集 二章很突兀】
评分对NIO的基本概念和特性进行了总体的介绍,是NIO入门学习的首选。
评分也是学过nio的人了
评分作者还是比较了解操作系统的。碍于 java 操作底层的不便,不得不设计了 NIO 实现 tcp buffer 和 多路服用,pipe 。
评分囫囵吞枣了一把,buffer/channel/selector/regex/charset
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
评分这本书是介绍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...
评分这本书首先介绍了操作系统层面上的IO原理, 然后详细的分析了NIO的各个方面, 包括缓冲区, 字符集, 选择器, 选择键, 也对NIO使用过程中常见的错误和陷阱做了标注. 这是一本难度不高的书, 值得所有java程序员阅读, 尤其是需要编写网络层代码的程序员. 我曾多次在工作中使用NIO做...
评分虽然这是一本比较旧的书,讲解的内容也是比较老的 - JDK 1.4引入的NIO机制,现在的JDK7都已经是异步IO了。但是对于不太了解NIO的同学还是可以去读一读。第一章和第四章我觉得讲解的最好,特别是第四章,将select调用相关的知识都覆盖到了。后面第五,第六章可以不看。想了解正...
