    Default How to Delete selected table data from DB???? HELP

    I'm trying to delete a selected row from a jTable that was queried from a database. I'm getting stuck on how to create an actionlistener that deletes the selected (highlighted) data from the database, here is what I have. I know after the connection it is probably totally wrong but I think you can get the idea from it....

     private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {   
     
     
     
    DefaultTableModel model=(DefaultTableModel)jTable1.getModel();
            try{
               Class.forName("java.sql.Driver");
               Connection con=DriverManager.getConnection ("jdbc:mysql://Lane-PC:3306/JavaApp","user","user");
     
           PreparedStatement ps = con.prepareStatement("DELETE FROM supportTickets (?,?,?,?,?,?)");
             ps.executeUpdate(jTable1.getSelectedRows());   
            }
     
           catch (SQLException se){
                JOptionPane.showMessageDialog(null,"SQL Exception, Database Connection Error","error",JOptionPane.PLAIN_MESSAGE);
     
               while (se !=null){
                   System.out.println("State :"+ se.getSQLState());
                   System.out.println("Message :"+ se.getMessage());
                   System.out.println("State :"+ se.getErrorCode());
     
                   se = se.getNextException();
     
               }
            } catch (Exception e){
                System.out.println(e);
            }
        }
