    From http://docs.oracle.com/javase/6/docs/api/java/util/TreeMap.html#keySet() :

    Returns a Set view of the keys contained in this map. The set’s iterator returns the keys in ascending order.

    If for some reason you need the keys in descending order, you can use descendingKeySet()

    If you want to iterate over the values, you can use entrySet()

    (Wow, I didn’t know that Map isn’t a Collection before…)
