【汇智学堂】基于TCP协议+多线程实现的一对多聊天

Server端

package com.huizhi;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class Server extends PublicUi{
    //private  static Socket socket;
    public static void main(String[] args) throws IOException, InterruptedException {
        // TODO Auto-generated method stub

        ServerSocket ss = new ServerSocket(10086);
        Server server=new Server("服务端","server answer");
        System.out.println("服务器正常启动。。。");

        while(true){
            Socket socket = ss.accept();
            System.out.println("用户接入成功。。。");
            /*
             * 每次连接成功一个客户端，则启动一个线程为其服务
             */
            ServerThread st1=new ServerThread(socket,server);
            st1.start();
        }
    }

    public Server(String a,String b){
        super(a,b);
    }
}

Server线程端- ServerThread

                inta=1;//标记为当前的socket对象
            }

        } catch (IOException e) {

客户端

import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;

public class Client extends PublicUi{
    private static Socket socket;

        }

        String strName="client"+Math.random();
        Client client=new Client(strName,"i want to speak:");

        try {

        } catch (Exception e) {

            }
            System.out.println("Client read = "+str);
            jTextArea.append("服务器回复说："+str+"\n");
