Recently I have learned that an ArrayList is acually better than a Vector because it is faster. Does anyone know why Sun would not have included a method in there JTable to accept ArrayLists as parameters?

good question
maybe because of backward compatibality.....
anyway it is very annoying to use the Vectors when constructing a JTable and i agree with you.

hi,
Vector is synchronized while ArrayList is initially not. If they would accept an ArrayList as argument they would have to make sure that it's synchronized. Not, that this is a big problem.
I think they just didn't change the implementation of DefaultTableModel which uses Vector though they are propagating the use of ArrayList to everyone else.
Anyway, as Vector is a subtype of collection it's not that difficult to use ArrayLists and initialize a JTable using a vector, nonetheless:
ArrayList data = new ArrayList();
JTable table = new JTable(new Vector(data));
Another possibility is to create your own TableModel which uses a synchronized ArrayList or HashMap or whatever is the most efficient container in this case.
cheers
