If you want to preserve the order of first appearance, assuming "vector"
is the original data:

Set<String> set = new LinkedHashSet<String>(vector);

If you don't care about order, you can use HashSet instead of LinkedHashSet.

I agree with the suggestion that, if at all possible, you should use a
Set instead of the Vector.
