Is there a storage class that counts occurrence of an item?  It don't seem
to see any, it seems kind of odd.

i.e.,

LinkedList<String> words;
words.add("one");
words.add("two");
words.add("one");
System.out.println(
   "the work 'one' appears this many times: "+
   words.count("one"));

I know it is trivial to implement, but it just seems that it should be a
part of the Collection or List interface.

Thanks,
