1、Java网络通信代码总结//建立服务器类，并令端口为2000ServerSocketserver=newServerSocket(2000);//使用accept阻塞方法监听客户端请求Socketincoming=server.accept();BuffeReaderin=newBufferReader(newInputStreamReader(incoming.getInputStream()));PrintWriterout=newPrintWriter(incoming.getOutput

2、Stream(),true);in.close();out.close();incoming.close();//建立客户端请求Socketsocket()=newSocket("192.168.1.1",2000);in=newBufferReader(newInputStreamReader(socket.getInputStream()));out=newPrintWriter(socket.getOutputStream(),true);//建立用户界面try{ServerSockets
