如何在java中的if语句中使用Jbutton

我正在尝试使用Jbutton操作侦听器clicks for将按下的变量从0设置为1、2或3。如果此号码已切换，则文本字段上的卡片套件将被切换。我的问题不是将按下的变量设置为新的数字，而是将其保持为0

您将pressedNumber的值从CardApp传递到Hand，但从未实际使用它

public int Discards(int pressedNumber) {
    Randomizer();
    return pressed;
}

你是不是想做一些像

public int Discards(int pressedNumber) {
    pressed = pressedNumber;
    Randomizer();
    return pressed;
}

现在，不可否认，我几乎没有睡眠，所以我很容易困惑，但我真的不知道你的问题是什么。您是否询问pressedNumber的值是否大于单击的按钮的值？它不应更改？你说要将其保持为0，但如果你只是想将其保持为0，为什么还要更改该值？不，我不想将其保持为0，我希望在单击其中一个按钮时更改该值。你将pressedNumber传递给HandDiscards，但从未实际使用它？你从未设置Hand.pressed；你想把作业放在丢弃方法中吗？是的，但我正在尝试使用它，尽管欢迎来到我的俱乐部：P@AngelaRucci这是一个很大的俱乐部。
