Need Help converting objects in a TreeMap to String

Question

This app counts the number of times a word occurs in a document. I used a HashMap to store the key and value. The I sorted them using TreeMap. Now I need to return the key (String) and value (Integer Object) so they may be print like this -- 'key: value'.
Example:
that: 3
This mean the word 'that' appeared 3 times in the document. Below is my toString() method. TreeMap sorts everything for me but I cant return 'map' because it is not a String. So I iterated through each key and value in the map. But now I dont know how to put all the iterations into 1 String value. I would greatly appreciate any help. Code below.
Thanks in advance.
public String toString() {
Object key = null;
Object value = null;
map = new TreeMap(map);
Set getKeys = map.keySet();
Iterator iterKeys = getKeys.iterator();
while (iterKeys.hasNext()) {
key = (String)iterKeys.next();
value = map.get(key))
return; // i need to return a String here
} // end toString()
} // end class
