"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Vector.setSize() can also increase the size of the vector by adding null elements at the end. I would not have much of a use for that method. Looks like it's been around since the very early days of Java, when the designers didn't quite have a handle on how collections should work.

Vector, in general, is a little crummy and ArrayList should be used instead, in most cases.
