Trying to populate a JTable

Question

Hello
Im having some issues populating a JTable.
I know that one of the ways to populate it is using the constructor JTable(Object[][] rowData, Object[] columnNames)
All the exmples I�ve seen on the net initialize the arrays this way
private String[] columnNames = {"","First Name","Last Name","Email"};
private Object[][] rowData = {
{"Mary", "Campione","Snowboarding", new Boolean(false)},
{"Alison", "Huml","Rowing", new Boolean(true)},
{"Kathy", "Walrath","Knitting", new Boolean(false)} };
that works fine, the problem is that Im trying to display more that 8000 records from a Database
and I can�t initialize the data array that way so I created a loop that pupulates the array and here is where the issue starts
One of the Colums needs to be a checkbox, and I know that in order to display the check box I need to store a boolean value into the Object array (data)
however if I do the following i get an error message
Object data[][] = new Object[rows][cols];
data[row][col] = new Boolean(false);
with the above code I get an ArrayStoreException which I know what It means, whowever how come when I initialze the array the first way it works
and the second way doesn�t work ?
Can someone helps?
Thanks

Don't forget to use the [Code Formatting Tags|http://forum.java.sun.com/help.jspa?sec=formatting], so the posted code retains its original formatting.

You should be using Vectors. You can search the forum for my "Table From Database" (without the spaces) example posted in the forum.
