在NetBeans中使用JTable通过鼠标单击事件更新mySQL数据库中的数据

Question

I am writing a code in netbeans wherein when clicked on a specific row the data is automatically updated from 'N' to 'Y' in mySQL database. I have written the following code. Please see if there's anything wrong with it. Tried using debugger, but it is not even going inside the click count loop.

private void jTable2MouseClicked(java.awt.event.MouseEvent evt) {                                     
    // TODO add your handling code here:
    PreparedStatement ps;
    ResultSet rs;
    if(evt.getClickCount()==2){

        int getsel = jTable2.rowAtPoint(evt.getPoint());
        int value = Integer.parseInt(jTable2.getValueAt(getsel, 6).toString());
        try{

            ps = con.prepareStatement("select * from roomservice where guestid = "+value);
            rs = ps.executeQuery();
            if(rs.next()){
                String taskstatus = rs.getString("taskstatus");
                if(taskstatus.equalsIgnoreCase("Y")){

                    ps = con.prepareStatement("update roomservice set taskstatus = 'N' where guestid= "+value);
                    ps.executeUpdate();

                    JOptionPane.showMessageDialog(null, "updated task status");

                }else if(taskstatus.equalsIgnoreCase("N")){
                    ps = con.prepareStatement("update roomservice set taskstatus = 'Y' where guestid= "+value);
                    ps.executeUpdate();
                    JOptionPane.showMessageDialog(null, "updated task status");
                }
            }
        }catch(Exception e){
            JOptionPane.showMessageDialog(null, e);
        }

    }
  }

Looking at https://docs.oracle.com/javase/7/docs/api/java/awt/event/MouseEvent.html

clicking twice does not make the click count two - try press mouse button one , press mouse button two, then release buttons
