Golf Ball Allocation
Monitor
At a golf club, players
can hire golf balls for their game from the club and return them to the club
after use. The better players, who tend not to lose any balls, only hire one
or two. The less experienced players hire more balls, so that they will have
spares during the game in case of loss. They are, however, required to buy replacements
for the lost balls so that they return the same number that they originally
hired. The golf balls are kept by the club groundsman, who turns out to be a
techie. He decides to treat the players as Java threads and to write a monitor
to allocate golfballs to players, if available, or to delay the players if insufficient
are available.
