Java Swing, como criar um método Dao do login?

public class MeuDao {
    public void metodoDoDao() {
        Connection con = ConnectionFactory.getConnnection();
        String sql = "SELECT login, senha FROM tbl_login WHERE login=? AND senha=? ";
        PreparedStatement pst = null;

        ResultSet rs =null;
       
        try {
            //con = DriverManager.getConnection("jdbc:mysql://localhost:3306/db_login", "root", "123");
            pst = con.prepareStatement(sql);
            
            pst.setString(1, jTextField_Username.getText());
            pst.setString(2, String.valueOf(jPasswordField_Password.getPassword()));
            rs = pst.executeQuery();
            if(rs.next()){
                JOptionPane.showMessageDialog(null,"username and password matched");
                jLabel_Message.setText("Login Successfully");
                jLabel_Message.setForeground(Color.GREEN);
                timer1.start();
                new MenuView().setVisible(true);
                
            }else{
                JOptionPane.showMessageDialog(null, "username and password do not matched");
                jLabel_Message.setText("Invalide Username Or Password !!");
                jLabel_Message.setForeground(Color.RED);
                timer1.start();
            }
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(null,ex);
        }
        
    }
}

public class MinhaClasse {
    private MeuDao meuDao;
    public void meuMetodo() {
        meuDao = new MeuDao();
        meuDao.metodoDoDao();
    }
}

public class MeuFrame extends JFrame {
    private MeuDao meuDao;
    private void jButton_LoginActionPerformed(java.awt.event.ActionEvent evt) { 
        meuDao = new MeuDao();
        meuDao.metodoDoDao();
    }
}

Tentei mas o setText, setForeground ficam com erro can not find the symbol), quando feitos no Dao:

public void fRMLogin(Object jTextField_Username, Object jPasswordField_Password, Object jLabel_Message){
        Connection con = ConnectionFactory.getConnnection();

        PreparedStatement pst = null;

        ResultSet rs =null;
        String sql = "SELECT login, senha FROM tbl_login WHERE login=? AND senha=? ";
        
       
        try {
            
            pst=con.prepareStatement(sql);
            
            pst.setString(1, jTextField_Username.getText());
            pst.setString(2, String.valueOf(jPasswordField_Password.getPassword()));
            rs = pst.executeQuery();
            if(rs.next()){
                JOptionPane.showMessageDialog(null,"username and password matched");
                jLabel_Message.setText("Login Successfully");
                jLabel_Message.setForeground(Color.GREEN);
                //timer1.start();
                new MenuView().setVisible(true);
                
            }else{
                JOptionPane.showMessageDialog(null, "username and password do not matched");
                jLabel_Message.setText("Invalide Username Or Password !!");
                jLabel_Message.setForeground(Color.RED);
                //timer1.start();
            }
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(null,ex);
        }
    }

public void fRMLogin(String username, String password){
...
}

frmLogin(jTextFieldUsuario.getText(), jTextFieldSenha.getText())
