It would be helpful to identify on which line each error occurs.

However, in this case, the problem is as I suspected.  The identifier
"event" is not directly visible.  The full name "java.awt.event" is
usable (because you "with" ed it), and the entities declared
inside java.awt.event are directly visible (because you "use"d it),
but the name "event" itself is *not* directly visible.  You can
do any of the following:
  1) use the full name "java.awt.event" instead of "event";
  2) drop the use of "event" in "event.UP" and say simply "UP";
  3) add a "use" clause for "java.awt" which will make the package
     names "event", "component", "color", and "graphics" directly visible.
