提问by Zarkopafilis
JPanel.add(ButtonGroup);
Is not working. I MUST add it to a JPanel because I am using tabs. This is getting really frustrating.I hace not found a way yet
不管用。我必须将它添加到 JPanel，因为我使用的是选项卡。这真是令人沮丧。我还没有找到方法

As ButtonGroup is not a component, you cannot add your ButtonGroup to a JPanel. Instead add your buttons to your JPanel, e.g:
由于 ButtonGroup 不是组件，因此您无法将 ButtonGroup 添加到 JPanel。而是将您的按钮添加到您的 JPanel，例如：
JPanel jPanel = new JPanel();
ButtonGroup group = new ButtonGroup();
btn1 = new JRadioButton("btn1 ");btn1.setSelected(true);
btn2 = new JRadioButton("btn2 ");
group.add(btn1 );
group.add(btn2 );
jPanel.add(btn1);
jPanel.add(btn2).
Hope it will be useful.
希望它会很有用。
Thanks
