Initializing Vector with ResultSet(TO SLOW!)

Question

Hi
Im creating a JTable from two Vectors. I need to initialize
the one vector from a resultset. This is way to slow for large result sets. Heres my loop:
private Vector getData(int columns[]) throws Exception
     rows = new Vector(queue.count);
     while (res.next())     
         Vector newRow = new Vector(columns.length);
         for (int i = 0; i < columns.length;i++)  
           newRow.addElement(res.getString(columns));
rows.addElement(newRow);
return rows;
Any Ideas to speed this up a bit.
Thanks!

I tested your code using String[][] rows (instead of Vector rows) hoping using arrays will make it faster. But it did not. What really did improve the performance was declaring and alocating memory for String[][] rows before calling the function. That is to say, the most time is spent on rows = new String[ROWS][COLS]. If you your conditions allow you to use String[][] rows instead of Vector rows and allocate memory for String[][] rows before calling your method getData(), then, in my opinion, it will improve the performance.
