 try{
                String sql="SELECT * FROM username WHERE name=?";

                System.out.println(lll);
                prst.setString(1,lll);

                prst.execute();
                rs = prst.executeQuery();
                if (rs.next()){

                    if( String.valueOf( regi.getPassword()).equals(rs.getString(3))){
                   
                        JOptionPane.showMessageDialog(Main, "成功", "错误",JOptionPane.WARNING_MESSAGE);
