急求Java socket编程实现两个客户端通信通过服务器转发不要图形界面不用连接数据库

实现两个客户端通信通过服务器转发不要图形界面不用连接数据库 求源码

可以找本java的书照着代码敲敲看

Android Socket 编程(WIFI 和 ADB)
这里提供了服务器端的源代码，客户端可在网上查找一下。

这个问题问得好，不太好回答

这个简单，实例代码，服务器端:

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

public class ChatTTCPServer {
    public ChatTTCPServer(int port, String name) throws IOException {
        ServerSocket server = new ServerSocket(port);
        Socket client = server.accept();
        if(client!=null){
            new ChatTTCPSocketJFrame(name, client);
            System.out.println("收到消息。。。");
            server.close();
        }
    }

    public static void main(String[] args) throws IOException {
        new ChatTTCPServer(9999, "Jack");
    }

}

客户端：
