SwingTimer在触发时只调用三个方法中的两个

Question

我正在编写一个简单的轮盘游戏，用户可以在其中添加玩家、下注和旋转轮盘(表示为JLabel，它更新文本以显示轮盘号码(

public void spin(int wheelSize, int initialDelay, int finalDelay,
    int delayIncrement, WheelCallback callback) {
    Random rand = new Random();
    int curNo = rand.nextInt(wheelSize) + 1;
    int finalNo = 0;
    int count = 10;
    assert (curNo >= 1);
    Listener myListener = new Listener(callback, this, curNo);
    myListener.start(finalDelay);

类别Listener:

package model;
import java.awt.event.*;
import javax.swing.*;
import model.interfaces.*;
import model.GameEngineImpl;
import model.WheelCallbackImpl;
public class Listener implements ActionListener {
WheelCallbackImpl callback;
GameEngineImpl engine;
Timer timer;
int delay, curNo, finalNo;
int count = 10;
public Listener(WheelCallbackImpl wheelcall, GameEngineImpl newEngine, int number) {
    callback = wheelcall;
    engine = newEngine;
    curNo = number;
}
public void actionPerformed(ActionEvent e) {
    if (count == 0) {
        engine.calculateResult(finalNo);
        callback.result(finalNo, engine);
        callback.playback();
        timer.stop();
    } else {
        callback.nextNumber(curNo, engine);
        curNo++;
        finalNo = curNo;
        count--;
    }
}
public void start(int delay) {
    timer = new Timer(delay, this);
    timer.start();
}
}

Listener与助手类WheelCallbackImpl通信，后者处理用户反馈并与我的View:通信

 public class WheelCallbackImpl implements WheelCallback {
Wheel wcWheel = Wheel.myWheel;
public void nextNumber(int nextNumber, GameEngine engine) {
    String strNo = Integer.toString(nextNumber);
    assert (nextNumber >= 1);
    System.out.println(nextNumber);
    wcWheel.setCounter(strNo);
}
public void result(int result, GameEngine engine) {
    System.out.println("callback.Result is running!");
    Collection<Player> players = engine.getAllPlayers();
    Player[] playerList = players.toArray(new Player[0]);
    System.out.println("Player list length is " + playerList.length);
    for (int i=0; i < playerList.length; i++) {
        if (playerList[i].getNumberPick() == result) 
            wcWheel.storeResults(playerList[i].getPlayerName(), playerList[i].getPoints(), " won!", i);         
        else
            wcWheel.storeResults(playerList[i].getPlayerName(), playerList[i].getPoints(), " lost!", i);
    }
    System.out.println("callback.result finished!");
}
/*
    Called by the controller - calls the GUI display/replay prompts
*/
public void playback() {
    System.out.println("Playback called!");
    int n = 0;
    while (n == 0)
        wcWheel.playAgain();
}
}

我的Timer能够成功地更新我的JLabel，但是当它执行if (count == 0)块时，它似乎只调用前两个方法，剩下的输出是：

6
7
8
9
10
11
12
13
14
15
Calculate result called!
callback.Result is running!
Player list length is 1
callback.result finished!

知道这里发生了什么吗？

Answer 1

如果一切都如您所发布的，那么在我看来这是一个不可能的结果：

callback.result(finalNo, engine);
callback.playback();

您说调用了callback.result()，其最后一条语句是在控制台上可见的System.out.println()，但是callback.playback();的第一条System.out.println()语句在控制台上不可见。

要么您修改了代码但没有重新编译，要么callback.playback()的结果是可见的，但您需要滚动控制台窗口才能看到它。
