how to get the length of a JTable

Question

I'm working with sql and java. I created a JTable to filtrate information from database to there. I want to get the length of that JTable (number of rows) and print that result in a JLabel. How can I do that?

Thanks!

It's worth reading about How to Use Tables and find more sample code on it.

Sample code:

TableModel dataModel = new AbstractTableModel() {
    public int getRowCount() { return rowData.length; }
    ...
   // override other method as well
}
JTable table = new JTable(dataModel);
JScrollPane scrollpane = new JScrollPane(table);

Simply call the DefaultTableModel#getRowCount() method to get the number of rows.
