Not Clearly understanding the problem can anyone explain it.?

1. In method calculateHorsesFinished(), you have to run a loop for each horse in the list and check whether each horse has finished or not (use isFinished() method for this). - If the horse is finished, then increment the count finishedCount. - If the horse is not finished, then: - Display "Waiting for " + horse.getName(). - Wait for the horse to finish. (Think about what to write here to make the program wait.)
