Question : filter sortedMap

I have a sorted Map like this:

SortedMap<String, SortedSet<String>> map = new TreeMap<String, SortedSet<String>>();

I filled the map from a file
-later I want to filter the map using a list of keys
- then write back the map to the file

I need your help for a simple and elegant way to do that .

Thanks
