You need to use the addAll() method, to put the *content* of a Collection into a Vector. The add() method puts the Collection itself in.

Unless you are using legacy code that forces you to use Vector, you should never use Vector. Use ArrayList, LinkedList or some other modern implementation of List.

A bartender will shortly be complaining about your obviously-false display name. Do yourself a favour and put in a real (sounding) one, before they do.

Lastly, this is not an advanced issue. Wrong forum.

It is sorta covered in the JavaRanch Style Guide.
