Well, you should not be using a 2D array for this purpose. You don't know how many rows are in your database so you don't know how big to make the array.

Instead you should be using a Vector of Vectors. The main Vector is used to hold the rows of data. Then for each row in the ResultSet you create another Vector and get all the value for that row. Then you add the row vector to the main vector.
 
It is sorta covered in the JavaRanch Style Guide.
