Java中的重置单选按钮

我有三个单选按钮在一个按钮组。我想在

JButton

上单击，将单选按钮重置为未填充。我尝试了你提出的逻辑建议，键入

.set

，所有的布尔值都没有达到我想要的效果。如果您有任何建议，我们将不胜感激。谢谢

请张贴您迄今为止尝试过的内容，我尝试过（错误）；setContentAreaFilled（假）；按钮。重新验证（）；button.firePropertyChange（null、true、false）；setIconPainted（假）；还有一些我想不起来了。请把你到目前为止尝试过的东西贴出来，我试过了（错）；setContentAreaFilled（假）；按钮。重新验证（）；button.firePropertyChange（null、true、false）；setIconPainted（假）；还有一些我想不起来了。哦，天哪，你太棒了。我完全忘了检查按钮组本身能做什么。谢谢你：天哪，你太棒了。我完全忘了检查按钮组本身能做什么。谢谢：D
