我无法从phpmyadmin本地主机数据库访问用户电子邮件和密码这是我的登录按钮代码

private void jButton2LoginActionPerformed(java.awt.event.ActionEvent evt) {                                              

    Connection con=myConnection.getConnection();
    PreparedStatement ps;
    ResultSet rs;
    try {

      //Selecting UserName and Password From DataBase 

      ps =con.prepareStatement("SELECT `userName`,` Password` FROM           
        `user` WHERE `userName` = ? AND `password`= ? ");

       ps.setString(1, jTextFieldUserName.getText());

       ps.setString(2,String.valueOf( jPasswordField1.getPassword()));

        rs=ps.executeQuery();

         if(rs.next()){

          MyContactForm mcf=new MyContactForm();
            mcf.setVisible(true);

             mcf.pack();
            mcf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            mcf.jLabel2UserName.setText(rs.getString(1));

            this.dispose();
       }else{
           JOptionPane.showMessageDialog(null,"Login Error");
       }

    } catch (SQLException ex) {
        System.out.println(" Error");
        Logger.getLogger(LoginForm.class.getName()).log(Level.SEVERE, null, ex);
    }

}

错误:2018年12月27日中午12:54:00 front.loginform jbutton2loginactionperformed
严重:空
com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxerrorexception:未知列'
“字段列表”中的“密码”
