java迭代器迷你游戏

Question

    public static void updatePlayers() {

    Iterator iterator = waitingRoom.keySet().iterator();
    System.out.println("Test 1");
    while (iterator.hasNext()) {
    Player player = (Player) iterator.next();
    System.out.println("Test 2");
 if (player != null) {
        System.out.println("Test 3");
 player.getPA().sendString("@yel@Start:" + ((gameStartTimer * 3) + (timeRemaining * 3)) + "", 199);
 player.getPA().walkableInterface(197);
    }
}

所以我一直在研究这个小游戏，我不确定我的迭代器发生了什么，但由于某些原因它不起作用。

问题是这个

    while (iterator.hasNext()) {
    Player player = (Player) iterator.next();

实际上它没有加载测试2，因此由于某种原因这不起作用。

支持检查加载我的迷你游戏计时器的大厅。

public static void startGame() {
    if (getSaraPlayers() < 1 || getZammyPlayers() < 1) {
        gameStartTimer = GAME_START_TIMER;
        return;
    }
    gameStartTimer = -1;
    System.out.println("Starting minigame.");
    gameStarted = true;
    timeRemaining = GAME_TIMER / 2;
    Iterator iterator = waitingRoom.keySet().iterator();
    while (iterator.hasNext()) {
        Player player = (Player) iterator.next();
        int team = waitingRoom.get(player);
        if (player == null) {
            continue;
        }
        player.getPA().walkableInterface(-1);
        player.getPA().movePlayer(GAME_ROOM[team - 1][0] + Misc.random(3), GAME_ROOM[team - 1][1] - Misc.random(3), 1);
        player.getPA().movePlayer(GAME_ROOM[team - 1][0] + Misc.random(3), GAME_ROOM[team - 1][1] - Misc.random(3), 1);
        gameRoom.put(player, team);
    }
    waitingRoom.clear();
}
