I am having trouble implementing MasterMind (the game).  I designed a
class that adds to a JPanel multiple JComponents which each contain 4
circles.  Upon clicking a circle, the program prints an appropriate colored
circle that the user has selected over the circle.  The problem is that when
implementing it, I am only  allowed to let the user to click on one row at a
time, starting with the first row.  I've tried many things...should I
perhaps implement the MouseListener in a separate class rather than inside
the ...Is there an easy way to allow the user to click on one row at a time?
