好的，这是我的代码。现在我想要程序完成的是程序显示空白屏幕（我已经完成）然后当用户点击其中一个按钮并在该按钮上放置一个X.然后在程序中点击6次后将它们放入输入数组的模式进行转换，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前进。这个程序现在做的是它显示空白屏幕，然后当按下按钮时它显示X.我得到它检查一个按钮，但我不知道如何检查所有这些。那么我怎样才能检查每个按钮的文本。

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，然后像这样检查其上的文本集：

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
    }
}

希望你明白这个想法

如何获取按钮的来源并使其工作？
