Iterator class

Does anyone know the proper way to loop through a collection?
This is a code snippet from a program i am working on and im not sure why i cant use an Iterator on a TreeMap.

Code:

---

Map stringMap = new TreeMap();

  for(Iterator i = stringMap.iterator(); i.hasNext();){           
        if(stringMap.containsKey(key)){
            return stringMap.get(i.next());   
        }
      i.next();
  }

I can use it on a LinkedList with no problem.

Code:

---

    import java.util.*;
 
    public class Test{
        public static void main(String[] args){
          String greeting = "Hello";
          String departing = "GoodBye";
 
        List l = new LinkedList();
        l.add(greeting);
        l.add(departing);
     
      for(Iterator i = l.iterator(); i.hasNext();){           
        System.out.println(i.next());   
      }

---

Code:

---

Map stringMap = new TreeMap();

  for(Iterator i = (stringMap.values()).iterator(); i.hasNext(){           
        if(stringMap.containsKey(key)){
            return stringMap.get(i.next());   
        }
      i.next();
  }

---

try that. Map/TreeMap does not have an iterator method, but values() returns a Collection, which does have an iterator.

Thanks Bro. Works like butta. You da man..... :p
