The best way to iterate SortedSet / SortedMap in Java backwards

Tags:

I need to iterate through SortedMap's entry set (which is a SortedSet) backwards. The code I'm writing is extremely performance-sensitive, as it's going to be called from many places thousands times per second, maybe more. Any advice on doing it the fastest way?

How do you reverse a Sortedset in Java?

To sort TreeSet in descending order, use the descendingSet() method in Java. The descendingSet() method is used to return a reverse order view of the elements contained in this set.

In Java 1.6 you can use NavigableSet.
