Answer / muralisankar
Both are to navigate collection objects. But Enumerator you
can not manipulate where as in Iterator you can add and
remove objects.

Answer / siva thimmannagari
Iterator supports only hasNext(),
next() and remove() methods.
It is not synchronized.
Enumeration supports ONLY
hasMoreElements(), nextElement().
It is synchronized.

Answer / aslam
Iterator has an additional method remove() and also
iterator checks for the concurrent modifications which will
be useful in multi threaded applications.
while Enumerator is much faster for sequential
access over collection elements, because it doesnot have
the additional overhead of checking concurrent modifications
