You can add a mouse listener to the table and capture event over there with mouse event like below

table.addMouseListener
      (
        new MouseAdapter()
        {
          public void mouseClicked(MouseEvent e)
          {
            if (e.getClickCount() == 2)
            {
            }
            if (e.getClickCount() == 1)
            {
            }
          }
        }
      );
    }

and to capture selection event you can use

table.getSelectionModel().addListSelectionListener(...);

when is selected at least a row (or a click on at least a row is performed).

You should monitor changes to the row selection using the JTables ListSelectionModel via a ListSelectionListener. This will notify you when the selection is changed by the user using the mouse or the keyboard or if the selection is changed programmatically for some reason

See How to Write a List Selection Listener for more details

when a double click on a row is performed

The only way you can detect this is through a use of a MouseListener. Normally, users expect that a left mouse button click will do one action and the right mouse button will do something else.

You will want to use SwingUtilities.isLeftMouseButton or SwingUtilities.isRightMouseButton to determine what the user is actually doing.
