I think this will help you. This will give you the row number u have selected.

table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ListSelectionModel rowSM = table.getSelectionModel();
rowSM.addListSelectionListener(new ListSelectionListener() {
   public void valueChanged(ListSelectionEvent e) {
                    //Ignore extra messages.
                   if (e.getValueIsAdjusting()) return;

                    ListSelectionModel lsm = (ListSelectionModel)e.getSource();
                    if (lsm.isSelectionEmpty()) {
                        System.out.println("No rows are selected.");
                    } else {
                        int selectedRow = lsm.getMinSelectionIndex();
                        System.out.println("Row " + selectedRow
                                           + " is now selected.");
                    }
                }
            });
}

You'll need to use a MouseListener to determine which row is d-clicked on.

class MyMouseListener extends MouseAdapter
{
public void mouseClicked(MouseEvent event)
{
  JTable table = (JTable) event.getSource();
  if (event.getClickCount()==2)
  {
     int row = table.rowAtPoint(event.getPoint());
     System.out.println(Row d-clicked: "+row);
  }
}
}

Hi,
Thank for all of your proposal.
I can learn more from all of you.
And in this case, I suppose that objects' solution is suitable to me.
Another time, thanks all of you.
Good luck Bye
