Vector is a legacy class which has been added to collections and ArrayList is a collections.
The main difference is Vector class is synchronized and Arraylist isnt.
However u can get a synchronized version of ArrayList using the static functions in Collections.

Here's my Collections Crib Sheet drastially reduced from a Sun Tech Tip newsletter. I keep it handy rather than memorize 10 classes implementing 3 interfaces. It gives some brief tips about how to choose one collection type over another.
