I am fairly new to swing components. However, I have seen many examples where a radio button implements actionListener as well as itemListener. Which one is the correct way of handling events in such a case?
Which event type does JVM generate when a user clicks a radio button? Is it an action event or an item event?

It depends which listener(s) has(/have) been attached to the radio buttons! E.G. Either or both of
AbstractButton.addActionListener(ActionListener)/addItemListener(ItemListener).Aside: for this I'd recommend an
ActionListener.The
ItemListenerwill produce two events when a button in aButtonGroupis selected. One of the events is for the item which just got deselected.
