Java – which JRadioButton to select

I have several jradiobuttons in the button group

private ButtonGroup radioGroup= new ButtonGroup();
   private JRadioButton radio1= new JRadioButton("Red");
   private JRadioButton radio2= new JRadioButton("Green");
   private JRadioButton radio3= new JRadioButton("Blue");

   radioGroup.add(radio1);
   radioGroup.add(radio2);
   radioGroup.add(radio3);

How do I see which one is selected? Use system out. Println (radiogroup. Getselection()) I only get something like javax swing. JToggleButton $ ToggleButtonModel@32b3714 The content of the

Solution

From the selected buttonmodel, you can get the actioncommand string (if you remember to set it!)

// code not compiled,run,nor tested in any way
ButtonModel model = radioGroup.getSelection();
String actionCommand = (model == null) ? "" : model.getActionCommand():
System.out.println(actionCommand);

But this only works if you first set actioncommand For example

// code not compiled,nor tested in any way
String[] colors = {"Red","Green","Blue"};
JRadioButton[] radioBtns = new JRadioButton[colors.length];
for (int i = 0; i < radioBtns.length; i++) {
   radioBtns[i] = new JRadioButton(colors[i]);
   radioBtns[i].setActionCommand(colors[i]);
   radioGroup.add(radioBtns[i]);
   somePanel.add(radioBtns[i]);
}
