Java代码如何使用Socket多线程实现一个服务器程序呢?

实现思路:
    只需使用Socket 类的accept()方法
      ServerSocket类的MultiThreadServer(socketname)方法即可实现一个多线程服务器程序

import java.io.IOException;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
public class MultiThreadServer implements Runnable {
	Socket csocket;
	MultiThreadServer(Socket csocket) {
		this.csocket = csocket;
	}
	public static void main(String args[])
	throws Exception {
		ServerSocket ssock = new ServerSocket(1234);
		System.out.println("listening");
		while (true) {
			Socket sock = ssock.accept();
			System.out.println("Connected");
			new Thread(new MultiThreadServer(sock)).start();
		}
	}
	
	public void run() {
	try {
		PrintStream pstream = new PrintStream(csocket.getOutputStream());
		for (int i = 100; i >= 0; i--) {
			pstream.println(i +" bottles of beer on the wall");
		}
		pstream.close();
		csocket.close();
		}
		catch (IOException e) {
			System.out.println(e);
		}
	}
}
