    Default removing all buttons from buttongroup

    I'm trying to remove all the buttons from a buttonGroup but I'm having problems with the argument of the remove() method defined in the API:

    for(int i = 0; i < RadioButtonsGroup.getButtonCount(); i++){
     
     
    		RadioButtonsGroup.remove......???
     
    	}

    It seems there is no method to remove a button by index, any suggestion for a beginner?

    RadioButtonsGroup.remove ( AbstractButton ab );
    How do you store your buttons after creating them? In an array? ArrayList? Iterate the collection and remove index for each.

    the buttons are created from a List returned from port.getAvailablePorts(): (method from rxtx serial class)

    for (int i = 0; i < port.getAvailablePorts().size(); i++){
     
     
    	JRadioButtonMenuItem e = new JRadioButtonMenuItem(port.getAvailablePorts().get(i));
     
    	RadioButtonsGroup.add(e);
     
    	menuItem.add(e);}

    when I want to refresh the serial ports list, first I need to clear the button group, then rebuild it with the new buttons, but I can't clear it using remove() with values from port.getAvailablePorts() because they can change at any time.

    I will try to store the buttons in a separate ArrayList, so I will feed the remove() method with its values, then clear the Arraylist, fill the ArrayList with the new values from port.getAvailablePorts(), create and add the buttons to the button group.
