| Question: |
What
is an Iterator?
|
| Answer: |
Some
of the collection classes provide traversal
of their contents via a java.util.Iterator
interface. This interface allows you to
walk through a collection of objects, operating
on each object in turn. Remember when using
Iterators that they contain a snapshot of
the collection at the time the Iterator
was obtained; generally it is not advisable
to modify the collection itself while traversing
an Iterator. |
