TreeMap retrieval
Having populated a TreeMap with put(String key, Object value) calls, how do i retrieve the object using an iterator? or dont i?
at the moment:
tree.keySet().iterator() gets me the string keys..
tree.entrySet().iterator() gets me strings of "key=Object@DEADBEEF"
where key is the key, the equals sign is literal, the Object is the type, and DEADBEEF is a memory address..
i just want the object.. put i iterate the keys and perform a get() on every single one of them?

http://java.sun.com/j2se/1.4.2/docs/api/java/util/TreeMap.html#values()
Basically:
...
Collection treeValues = tree.values();
for (Iterator treeIter = treeValues.iterator(); treeIter.hasNext();
{...
}

i knew it was in there somewhere.. not to worry, as i later found out that i needed random access to the values in the map, so my initial desire to run 2 iterators in step and print the keys and the values, wasnt right anyway :)
thanks cma..
