At the moment I have a Tree Map consisting of a String and Integer,

TreeMap<String, Integer> frequencyData = new TreeMap<String, Integer>( );


The problem now is that I need to hold more than one integer for each string.
Is it possible to have:

TreeMap<String, List>

?

It seems to be possible but how do I add to the list?

Before I could do:

frequencyData.put(word,x);
(when it was string,integer)

but how do I add to the list?
