Ok so this is a really easy question but I just havent used hashtables before.  I have been looking at documentation and I am alittle confused.  I have a bunch of data stored in a hashtable.  Now I want to go through that data element by element and get it out of the hashtable.  I know that I have to use the hashtable get() method however I am not really sure how to do this because the part with the keys kind of confuses me.  I was trying to go through it simply like an array but it did not work.  Can someone kind of give me a hand on how to go through the hashtable with keys?  


Thanks!

Hashtable h = new Hashtable();
h.put("key","value");
// other h.put() calls;
Enumeration enum = h.keys();
while(enum.hasMoreElements()){
 Object key = enum.nextElement();
 Object value = h.get(key);
 System.out.println(key+":"+value);
}
