Java Socket最简单编程（实现单客户端聊天）

import java.net.*; import java.io.*; public class MyQQServer { /** * @param args */ public static void main(String[] args) throws Exception { ServerSocket server=new ServerSocket(5678); System.out.println("服务器已启动，请启动客户端"); Socket client=server.accept(); BufferedReader in=new BufferedReader(new InputStreamReader(client.getInputStream())); PrintWriter out=new PrintWriter(client.getOutputStream()); while (true) { String content=in.readLine(); System.out.println("收到消息:" + content); BufferedReader wt=new BufferedReader(new InputStreamReader(System.in)); out.println(wt.readLine()); //out.println("message from server:has received your message \"" + content + "\"" ); out.flush(); if (content.equals("quit")) { System.out.println("客户端已经退出此次会话.."); break; } } client.close(); server.close(); } }
