Java Lambda style

So, this doesn't work, since seatsAvailable is final. How can what I'm trying to accomplish be done using more of a lambda-style-from-the-ground-up way?

final boolean seatsAvailable = false;
theatreSeats.forEach(seat -> {
    if (!seatsAvailable) seatsAvailable = seat.isEmpty();
});

It looks like you want seatsAvailable to be true if there is at least one empty seat. Therefore, this should do the trick for you:

final boolean seatsAvailable = theatreSeats.stream().anyMatch(Seat::isEmpty);

(Note: I am assuming that your class is named Seat.)
