Once you address the question of storing a null value in the Map, the only remaining question I have is whether to use
a LinkedHashMap instead of an ordinary HashMap. In general, I like the predictability of a LinkedHashMap for maps that
are iterated, but in this case, I don't feel strongly about it one way or the other.
