Question
How to manage two JRadioButtons in java so that only one of them can be selected at a time? Is there any method in java to take care of this or you need to build your own logic?
Solution
You have to add them in a ButtonGroup
ButtonGroup group = new ButtonGroup();
group.add(birdButton);
group.add(catButton);
Ensure you add this code after the buttons are created using the new JRadioButton
constructors, as appropriate.
OTHER TIPS
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.
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.
