While order is not guuranteed, you can actually loop over a Vector using 
a for loop and the Vector elementAt(int index) method. Besides, if you 
create a [Array|Linked]List from the Vector, you would get the same 
order. If you want to use an Iterator, Vector implements the iterator() 
method as well.

The only difference between Vector and ArrayList is that Vector is 
synchronized (threadsafe) and ArrayList is not.
