Yes, that was a useful post.  I also note some other interesting methods:

static <T> Enumeration<T> 	emptyEnumeration()
            Returns an enumeration that has no elements.

static <T> Iterator<T> 	emptyIterator()
            Returns an iterator that has no elements.

static <T> ListIterator<T> 	emptyListIterator()
            Returns a list iterator that has no elements.

There's methods to return empty collections too (List, Map, Set) as well 
as singletons for List, Map and Set, but I think more folks know about 
those.  The above methods I listed are new with Java 1.7.
