Java之IO/NIO五种模型必须了解的基础概念

Java IO/NIO阻塞IO模型最传统的一种IO模型，即在读写数据过程中会发生阻塞现象。当用户线程发出IO请求之后，内核回去查看数据是否就绪，如果没有就绪就会等待数据就绪，而用户线程就会处于阻塞状态，用户线程交出CPU。当数据就绪之后，内核就会将数据拷贝到用户线程，并且返回结果给用户线程ÿ...

请问java 普通IO操作与NIO性能差别有多少，如何优化？

java io与nio：报错

小弟对IO不熟悉，所以想问问各位大虾，传统IO的字符流不是也有buffer吗，和NIO的buffer有什么不同？其次就是我实现一个简单的文件读取和输出操作，仅对这个功能来说，用IO和NIO来实现的区别在哪，非阻塞的优势怎么体现? 谢谢不甚感激

不学无数——Java中IO和NIO

JAVA中的I/O和NIO I/O 问题是任何编程语言都无法回避的问题，可以说 I/O 问题是整个人机交互的核心问题，因为 I/O 是机器获取和交换信息的主要渠道。在当今这个数据大爆炸时代，I/O 问题尤其突出，很容易成为一个性能瓶颈。什么是I/O I/O ? 或者输入/输出 ? 指的是计算机与外...

Java IO与NIO 学习

面向流与面向缓冲　　Java NIO和IO之间第一个最大的区别是，IO是面向流的，NIO是面向缓冲区的。 Java IO面向流意味着每次从流中读一个或多个字节，直至读取所有字节，它们没有被缓存在任何地方。此外，它不能前后移动流中的数据。如果需要前后移动从流中读取的数据，需要先将它缓存到一个缓冲区。...

关于java流的几个概念：IO、BIO、NIO、AIO，有几个人全知道？

关于同步、阻塞的知识我之前的文章有介绍，所以关于流用到这些概念与之前多线程用的概念一样。下面具体来看看java中的几种流 IO/BIO BIO就是指IO，即传统的Blocking IO,即同步并阻塞的IO。这也是jdk1.4之前的唯一选择，依赖于ServerSocket实现，即一个请求对应一个...
