iterator anumeration difference code example

Example 1: iterator vs enumerator

Iterators allow the caller to remove elements from the underlying collection 
during the iteration with its remove() method. You cannot add/remove elements 
from a collection when using enumerator.
Enumeration is available in legacy classes i.e Vector/Stack etc. 
Iterator is available in all modern collection classes.
Another minor difference is that Iterator has improved method names e.g.
Enumeration.hasMoreElement() has become Iterator.hasNext(),
Enumeration.nextElement() has become Iterator.next() etc.
