BIO、NIO、AIO 有什么区别?
1、同步阻塞BIO一个连接一个线程。JDK1.4之前,建立网络连接的时候采用BIO模式,先在启动服务端socket,然后启动客户端socket,对服务端通信,客户端发送请求后,先判断服务端是否有线程响应,如果没有则会一直等待或者遭到拒绝请求,如果有的话会等待请求结束后才继续执行。2、同步非阻塞NIONIO主要是想解决B...

javaIO-字符流
2.1字符流为什么出现字符流?一个字符经过编码后可能占用不同的字节数,字符和字节不是一一对应的关系,编码后的字符有可能变成数量不等的字节使用字节流在操作文本文件的时候不是很方便,不能准确控制到底多少个字节对应一个字符?所以Java提供了专门用来操作字符的字符流(所以字符流只针对文本文件)能准确的从流中获取/...
