此工程为通信系统TC/IP协议 主要技术是纯java 主要用到的io流，输入流如：InputStream，InputStreamReader，BufferedReader等。输出流如：OutputStream，OutputStreamWriter，PrintWriter等 功能：主要是通过服务器端，客户端的通信，符合多线程的开发，请使用者放心使用 描述：此小项目用到了各种io流，对于学习流的人有极大帮助。-This works for communications systems

解决中文乱码主要是用OutputStreamWriter包在OutputStream的底层流，设置GBK编码读取-Solve Chinese garbled underlying OutputStreamWriter package OutputStream stream, set GBK code reading

An OutputStream that does Base64 encoding on the data written to it, writing the resulting data to another OutputStream.
