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.
