You have to add them in a ButtonGroup
您必须将它们添加到ButtonGroup 中
ButtonGroup group = new ButtonGroup();
group.add(birdButton);
group.add(catButton);
Ensure you add this code after the buttons are created using the new JRadioButtonconstructors, as appropriate.
确保在使用新JRadioButton构造函数创建按钮后添加此代码，视情况而定。

My java is rusty but if i remember correctly you have to use the ButtonGroup class. Add your radio buttons to ButtonGroup object. I think it will look like this.
我的 Java 生锈了，但如果我没记错的话，您必须使用 ButtonGroup 类。将您的单选按钮添加到 ButtonGroup 对象。我认为它看起来像这样。
ButtonGroup buttonGroup = new ButtonGroup();
buttonGroup.add(new JRadioButton('Label', false));
buttonGroup.add(new JRadioButton('Label2', true));
Hope this helps. I have abandoned Java years ago.
希望这可以帮助。几年前我已经放弃了 Java。
