我是java新手，所以我得向你求助。我正在创建一个非常简单的程序，但是我在验证密码和登录textfield时遇到了问题。我想知道那个代码怎么了，你能帮我吗？
控制器

package sample;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.PasswordField;

import java.awt.*;

public class Controller {
    @FXML
    public TextField login,password;
    public void LoginButtonClicked(ActionEvent event)
    {
    if(login.getText().equals("yes")&&password.getText().equals("yes"))
        {
            System.out.print("Congratulations");
        }
    else
        {
            System.out.print("no");
        }

    }

}
