Differences between ArrayList and Vector

Last friday, I posted the differences between HashMap and Hashtable. Studying a little more, I decided to checkout the differences between ArrayList and Vector. Surprise! The same three items, plus one bonus:

1. Vector is thread-safe, ArrayList isn't;
2. ArrayList supports null items;
3. Vector's enumerations are not fail-fast; and
4. You can pass the capacity increment to Vector's constructor.
