多线程服务器的准系统示例：

A barebones example of a multi-threaded server:

//MyServer.java
public class MyServer {

  private static int PORT = 12345;

  public static void main(String args[]) {

    ServerSocket s = new ServerSocket(PORT);
    while(true) new MyServerThread(s.accept());

  }

您的服务器主题：

//MyServerThread.java
public class MyServerThread implements Runnable {

  private InputStream in = null;
  private OutputStream out = null;

  public MyServerThread(Socket s) {

    in = s.getInputStream();
    out = s.getOutputStream();

    (new Thread(this)).start();
  }

  public void run() {
    //do stuff with **in** and **out** to interact with client
  }
}

此示例中缺少：

• 错误处理


• 关闭（）输入套接字/流


• 关闭服务器


• 客户端

• Error handling
• close()ing the sockets/streams
• shutting down the server
• the clientside

希望这会给你一些想法通常看起来如何。

Hopefully that gives you some idea of how it usually looks.
