你好厉害哦!你在工作还是在校?
你可以说明一下我的程序错在哪吗?
你的代码有点长,我看了有点

ServerSocket s=new ServerSocket(3333);
while(true){

n=n+1;
Socket client=s.accept() ;
list.add(client);
m m1=new m(client,n,list);

Thread th=new Thread(m1);
th.start();
System.out.println("connect!!");

｝你想为每个客户创建一个进程　为什么还在每个进程里用list增加用户呢？后一个线程里面都有前面的用户信息
　100个用户的话就有１００个线程同时监听客户一，不知道能不能行　自己在改下：）
楼上的楼上的程序　好眼熟啊

我用了类似你那种 for (int i = 0; i < list_1.size(); i++) {
Socket s = (Socket) list_1.get(i);

的方法,已经搞定了!!!!!!!!!

非常感谢!!!!!!!!!!!!
