Answer 1

private void JtableMousePressed(java.awt.event.MouseEvent evt) {

if (evt.getClickCount() == 2)  // double click
    {
        nextFrame a = new nextFrame(new javax.swing.JFrame(), true);
        a.setVisible(true);

        int selectedRowIndex = Jtable.getSelectedRow();
        Object selectedObject = (Object) Jtable.getModel().getValueAt(selectedRowIndex, 6);

    }

System.out.println(selectedObject);
