I've been looking at:

http://www.netbeans.org/kb/articles/mysql-client.html#db08

A DefaultTableModel uses

protected Vector dataVector
The Vector of Vectors of Object values.

for the data? So, that's where the data is, in dataVector?

//carTable is a JTable
carTable.setModel(CarTableModel.getInstance());

Should carTable now show data, providing that carTable.getDataVector()
returns data?

thanks,

I wasn't aware that I was using reflection. Is:

http://java.sun.com/javase/6/docs/api/java/util/Calendar.html#getInstance()

reflection?

I only want one CarTableModel, so it's a Singleton.

The CarTableModel.getInstance() returns the only CarTableModel.

If it matters, I can make the constructor public and instead have:

For a DefaultTableModel instance? Yes.

I didn't follow the tutorial carefully, but you still have to set the
dataVector field to something. See the setDataVector() method.

I have no idea what "getInstance()" is, did you add it yourself? It's
not in any of the docs that I can find.

Personally, these static variables weird me out. What if you need to
display two tables? Say the user is comparing two lists of cars, one
list from cars in rows 100-110 of the database (the cheap cars) and the
other table shows rows 340-350? How do you do that when there can only
be one table ever?

I think you should just get rid of the "INSTANCE" field in both cases,
and just call "new" on the class like a normal class. You should be
able to just make a table model and drop it into the JFrame's JTable,
kinda like this:

package jtabletest;
