enumerator vs iterator 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.
