好的，这是我的代码。现在我希望程序完成的是让程序显示空白屏幕(我已经完成了)，然后当用户单击其中一个按钮并在该按钮上放置一个 X 时。然后，单击 6 次后，程序会将输入的模式转换为输入数组，这样我就可以将输入数组与模式数组进行比较，并能够告诉用户其是否正确并继续。该程序现在所做的是显示空白屏幕，然后当按下按钮时显示 X。我让它检查一个按钮，但我不知道如何检查所有按钮。那么我如何检查每个按钮中包含的文本。

您可以在父容器上调用 getComponents() - 无论是面板、框架还是窗口，然后检查它是否是按钮的实例，然后检查其上设置的文本，如下所示:

Component[] comps = parent.getComponents();
for(Component c:comps){
    if(c instanceof JButton){
        JButton btn = (JButton) c;
        String text = btn.getText();
        //Use text for whatever, add it to an array or something
    }
}

希望你明白
