Vector and ArrayList are very similar. Both of them
represent a 'growable array',
ArrayList it's part of the Java Collection Framework, and
has been added with version 1.2, Vector it's an object that
is present since the first version of the JDK.
The main difference is that Vector it's a synchronized
object, while ArrayList it's not.
While the iterator that are returned by both classes are
fail-fast (they cleanly thrown a
ConcurrentModificationException when the original object has
been modified), the Enumeration returned by Vector are not.
Unless you have strong reason to use a Vector, the
suggestion is to use the ArrayList.
