socket多线程的问题

已采纳

java当中socket多线程是怎样写可以将所有客户发来的消息数记录下来并显示给客户，客户当前跟服务器说的是第几句话，比如第一个客户：０:０：ａａ
服务器回复ａａ
第一个客户：１:１：ｂｂ
服务器回复ｂｂ
第二个客户：２:０：ａａ
服务器回复ａａ
第二个客户：３:１：ｂｂ
第一个数是总行数，第二个是当前客户行数第三个就是内容了现在这个程序已经完成了后两个，第一个总行数咋实现 谁给发个代码啥的谢谢最好能在这里加

    具体代码 给你
    客户端
    import java.io.*;
    import java.net.*;

    public class Clinet
    {

    public static void main(String[] args) 
{
    InetAddress ia = null;
    Socket s = null;                                               
    BufferedReader is = null;
    BufferedWriter os = null;
    PrintWriter pw = null;
    BufferedReader br = null;
    BufferedWriter bw = null;

    try {
        ia= InetAddress.getByName("127.0.0.1");
        //          System.out.println(ia.getHostAddress());

        s= new Socket(ia, 9001);
        is = new BufferedReader(new InputStreamReader(s.getInputStream()));
        pw = new PrintWriter(s.getOutputStream(), true);
        br = new BufferedReader(new InputStreamReader(System.in));
        //            System.out.println("输入路径：");

    }

            }





    } catch (UnknownHostException e) {

    }

    服务器端
    import java.io.*;

    public class Sever {

    ServerSocket ss = null; 
    Socket  s = null;
    BufferedReader is = null;

    BufferedReader filebr = null;
    try

        System.out.println("加载中");
        s = ss.accept();

    可以再Server类里定义一个静态的变量，每次客户端来消息都将这个常量+1
