retrieve key from HashMap

[Ted Schrey]

if I have only one remaining key/value set in a HashMap (removed all others), how can I retrieve the key

[Ted Schrey]

I know I can print the key: mapName.keyset(), but I can't seem to assign it to a variable...

I tried something that seems to work, though it looks clumsy to me, I guess I'll use it.
Sorry for posting too quickly!

Set<Person> bestReviewerSet = rank.keySet();
Person bestReviewer = null;
for(Person p : bestReviewerSet){
bestReviewer = p;
}

How about going through the iterator that is returned from the keyset?
