服务器Server
客户端CLient
Server静态常量num
创建服务器，ServerSocket的端口号为8000，连接套接字。
每创建一个客户端，客户端就创建一个Socket，端口号为8000，与服务器进行连接，与此同时，客户端新建ServerSocket，端口号为3000+Server.num，连接套接字。
服务器与客户端连接后，服务器新建子线程Handler。
子线程Handler，新建ServerSocket，端口号为2000+Server.num，连接套接字。
每当有一个子线程创建，主线程都会加入一个子线程创建的对话界面（显示框，输入框，发送按钮）的选项卡
每当创建一个客户端，客户端都会创建一个对话界面
点击发送时，Hanlder会创建Socket，端口号为3000+Server.num。客户端会创建Socket，端口号为2000+Server.num
这是前提，现在我运行程序，但是当我每当创建一个客户端时，Server.num都不会改变，不知道怎么回事，急求大神解答，感激不尽！
以下是源代码，这里我讲Server.num抽离出去单独做成一个类NUM，每次Handler创建后，调用该类的增加函数numAdd()：
服务器代码：
package NewPackage;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
public class Server {
private ServerSocket serverSocket;
private int PORT = 8000;
private Thread workThread;
private static MyServer server;
public static ArrayList solist = new ArrayList();
public static ArrayList ctlist = new ArrayList();
public Server() throws Exception {
serverSocket = new ServerSocket(PORT);
}
public void service() {
while (true) {
Socket socket = null;
try {
String s;
int num = NUM.num;
NUM.numadd();
socket = serverSocket.accept();
System.out.println(num + 2000);
workThread = new Thread(new Handler(num + 2000, MyServer.jp));
workThread.start();
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void main(String args[]) throws Exception {
server = new MyServer();
server.CreateGUI();
new Server().service();
}
}
