Java - 设置BooleanProperty导致＆＃39; java.lang.StackOverflowError＆＃39;

Question

我不打算发布所有代码，只发布与之关联的部分。我对创建自己的听众并不太熟悉，本书还没有涉及到这一点。也许我做错了但你可以查看下面的代码并亲自看看。基本上当我改变它不断尝试设置值或一次又一次的值时，我试图用断点跟踪它，看看我是否能解决问题，但也许我错过了一些东西......追踪问题在那个特定的代码行设置了BooleanProperty值，并且每当我向前移动一行时就停留在那里。

这是我的Objects构造函数和数据字段

private BooleanProperty endTurn;

/** Constructor */
public PlayerHand() {
    // Set the Data Field values
    super.playerCards = new ArrayList<>();
    this.chips = 100;
    this.lastBet = 0;
    this.endTurn = new SimpleBooleanProperty(this, "endTurn", false);
}

这是getter，setter和property方法

/** Get whether the player has ended the turn */
public boolean getEndTurn() {
    return this.endTurn.get();
}

/** Set's the end of turn */
public void setEndTurn(boolean endTurn) {
    this.endTurn.setValue(endTurn);
}

/** Property getter method for ending the turn */
public BooleanProperty endTurnProperty() {
    return this.endTurn;
}

这是创建对象的类中的侦听器

    // Set the binds for each player
    for (int i = 0; i < players - 1; i++) {
        alPlayerHand.get(i).endTurnProperty().addListener(e -> {
            progressTurn();
        });
    }

编辑：我忘了添加这条线是否被卡住了

public void progressTurn() {
    // Have AI make their decisions and turn rules on and off
    if (alPlayerHand.get(playersTurn).getLastBet() == 0) {
        if (alPlayerHand.get(playersTurn).isLittleBlind() &&
                currentGameRound == 1) {
            alPlayerHand.get(playersTurn).setBet(littleBlind);
            lastPlayer = "Little Blind";
        } else if (alPlayerHand.get(playersTurn).isBigBlind() &&
                currentGameRound == 1) {
            alPlayerHand.get(playersTurn).setBet(bigBlind);
            lastPlayer = "Big Blind";
        } else if (alPlayerHand.get(playersTurn).isAI()) {
            alPlayerHand.get(playersTurn).decide();
            lastPlayer = alPlayerHand.get(playersTurn).getLastMove();
        }
    }
    // Add the last bet to the pot
    pot += alPlayerHand.get(playersTurn).getLastBet();
    alPlayerHand.get(playersTurn).setBet(0);

    if ((playersTurn + 1) <= players - 1 &&
        alPlayerHand.get(playersTurn).isAI()) {
        playersTurn++;
    } else if ((playersTurn + 1) > players - 1 &&
        alPlayerHand.get(playersTurn).isAI())
        playersTurn = 0;

    endTurn(); // Debug stops here and stays here
}

编辑：再次忘记代码

/** End the current players turn */
public void endTurn() {
    // End Players turn
    if (alPlayerHand.get(playersTurn).getEndTurn()) {
        alPlayerHand.get(playersTurn).setEndTurn(false);
    } else
        alPlayerHand.get(playersTurn).setEndTurn(true);
}

最后这里是错误 - 大多数已被删除，因为它只是重复了

我真的很感激任何关于我做错了什么的建议，这本书到目前为止只涵盖了绑定属性的创建......但从未涉及内部工作，只是如何在没有声明的情况下设置方法可见。

基本上我想要玩家进行移动，如果玩家是AI控制的，那么计算机做出决定，并且在任一结束时它设置endTurn值，然后使得侦听器调用progressTurn方法并且循环继续

Answer 1

当我在endTurn（）方法的if语句中调用getter获取boolean属性时，我假设它正在启动我的监听器，所以我所做的是用'if（playersTurn％2 ==）替换它0）'
