This is best achieved by using an image editing program to map out the "hot spots" and then code these into your program</p> <h2>You could...</h2> <p>Use a <code>JLabel</code> to render the board image and attach a <code>MouseListener</code> to it.</p> <p>The problem I would have with this is trying to figure out how to update the image with the player markers.</p> <h2>You could...</h2> <p>Use a <code>JPanel</code> and override it's <code>paintComponent</code> to render the image and player moves/markers.</p> <p>You would then add a <code>MouseListener</code> to it and monitor the mouse clicks from there.</p> <p>Regardless of which method you used, I would probably create a <code>List</code> of <code>Rectangle</code>s which represented the hot spots the user can click. Each time <code>mousePressed</code> is called, I would walk this list and use <code>Rectangle#contains(Point)</code>, passing the mouse click point, to determine which hot spot was clicked.</p> <p>You would then to to compare this with the game model to determine if it's a valid move or not and take appropriate action as required.</p> <p>Take a look at <a href="http://docs.oracle.com/javase/tutorial/uiswing/events/mouselistener.html" rel="nofollow">How to write a Mouse Listener</a> and <a href="http://docs.oracle.com/javase/tutorial/uiswing/painting/" rel="nofollow">Performing custom painting</a> for more details</p>
