我是java的初学者，我在制作doClick按钮时遇到了一些麻烦。我不明白它是如何工作的，我需要在我的代码中使用它。
JButton easyb = new JButton("Easy");
JButton mediumb = new JButton("Medium");
JButton hardb = new JButton("Hard");
String fn = JOptionPane.showInputDialog("Choose your level \n", easyb.doClick() ,mediumb.doClick(), hardb.doClick() , "\n \n Easy are words you know everyday \n Medium are words that you have seen before \n Hard are words that you have rarely seen in your life");
我希望输出看起来像这样：
Choose your level
easy medium hard ( you can click on the words)
Easy are words you have said everyday
Medium are words that you have seen before
Hard are words that you have rarely seen in your life

如果您有以下任何问题的评论。
答案 0 :(得分：2)
您可以使用更好的JOptionPane，JOptionPane.showOptionDialog：
String[] options = { "Easy", "Medium", "Hard" };
int selection = JOptionPane.showOptionDialog(null, "Choose Something", "Title",
JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null,
options, options[0]);
// ***** oops! this should be >= 0, not > 0. Corrected!
if (selection >= 0) {
System.out.println("Selected: " + options[selection]);
}

来自您的评论：
按钮部分有效，但我有两个问题。首先，我不认为它会显示我希望输出如我在问题中所说的那样。这些词也必须存在。
您需要做的就是输入if / else块或者更好，一个switch语句根据选择的选项0,1或2输出正确的String。
例如，
if (selection >= 0) {
String word = options[selection];
case selection 0:
// output stuff based on easy
break;
case selection 1:
// output stuff based on medium selection,....
break;
//.... etc.../
}
第二个问题将显示整个代码，然后您就可以看到问题。
我看到了您的整个代码，但我没有看到与之相关的具体问题。

Ordous建议你用你的3个按钮创建一个JPanel，给它们ActionListeners，然后将JPanel放到JOptionPane或JDialog中，然后显示它。
