12,750 PointsYou are not printing the message that displays if not enough battery power remains.
In the try-catch block, print iae.getMessage() as you are doing when you check if the battery is empty.

204 PointsThanks Scott, now i understand when you say "print" I need to wrap it in the System.out method
