       Then use the variable to prevent the arrowKeyPressed event 
listener from taking action until the boolean variable becomes true, as 
shown here:

boolean must be true or arrow press is ignored

Of course, you will need to set the variable to true when your countdown 
is completed.  Then, the arrow keys will become active.
