title: JLabel click event
body: <p>If you have two <code>JLabel</code>s in a <code>JFrame</code> both with the same <code>MouseListener</code> click event added to them, how can you tell which <code>JLabel</code> was clicked without creating a second actionlistener?</p>
  
  <p>Note: both labels have the same text written on them so that cannot be used to tell them apart.</p>
