In preliminaryRound() you should call exceptionGenerator.runCourse(). If no exception is thrown, print out "No exception thrown". If the call to runCourse() resulted in a checked exception, print out "Caught checked exception". If runCourse() resulted in an unchecked exception, print out "Caught unchecked exception".

grandFinale() will consider what can happen when finding the ultimate winner. If the throwChecked parameter is true, your code should raise the checked exception If the throwUncheckedparameter is true instead, your code should raise an unchecked exception. If both parameters are false, nothing else needs to be done.
