While you can do this by iterating over the keys, make sure that you aren't
making your life harder by using the wrong container for the job. If you
use TreeMap (optionally synchronized by
Collections.synchronizedSortedMap()), then your entries in the map will be
ordered by their key, and all you have to do is call firstKey() to retrieve
the smallest key.
