我想在我的游戲中實(shí)現(xiàn)網(wǎng)絡(luò)功能，但是我有一個(gè)很大的問題。當(dāng)我嘗試創(chuàng)建 JFrame 組件時(shí)，在執(zhí)行網(wǎng)絡(luò)代碼后，它總是顯示為白屏。雖然網(wǎng)絡(luò)工作正常，但我無法讓 UI 以任何方式工作。這是網(wǎng)絡(luò)代碼：package progtech2bea;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.net.InetAddress;import java.net.ServerSocket;import java.net.Socket;public class NetworkController implements Runnable {public Main base;private MainMenu mm;private String ip;private int port = 22222;public int pnum;private Thread thread;private Socket socket;private DataOutputStream os;private DataInputStream is;private ServerSocket serversocket;private int errcount = 0;private boolean commerror;private boolean client;private boolean accepted = false;public void beginServer(String ip, MainMenu mm){    this.ip = ip;    this.mm = mm;    if (!connect()) {        initalizeServer();        pnum = 1;    }    else    {        pnum = 2;    }    thread = new Thread(this, "WaterWar");    thread.run();}@Overridepublic void run() {    while (true) {        tick();        //m.repaint();        if (!client && !accepted) {            listenServerRequest();        }    }}private boolean connect() {    try {        socket = new Socket(ip, port);        os = new DataOutputStream(socket.getOutputStream());        is = new DataInputStream(socket.getInputStream());        accepted = true;        mm.dispose();        base.showMain();        base.moveToP2StartView();        System.out.println("Successfully connected");    } catch (IOException e) {        System.out.println("No active server, initalizing new one");        return false;    }    return true;}如果網(wǎng)絡(luò)代碼沒有運(yùn)行，jFrame 工作得非常好。以下不起作用，它在單獨(dú)的類中被調(diào)用：//the jFrame component initalizing all the UI elements insideMain m = new Main(jTextField1.getText(),jComboBox1.getSelectedIndex());//calls the NetworkController's beginServer() method, trying to establish //connection/start a servernc.beginServer(jTextField2.getText(),this);有什么問題？
