JavaFX: Stage show()方法的问题

Question

在尝试从JavaFX的Stage类执行show()方法时，我遇到了很多错误。我正在使用Intellij IDEA。这是IDE生成的基本代码，我在尝试设置它时遇到了很多问题。我已经能够修复我必须处理的其他10个错误，但我不知道如何修复这个错误。

这是我的应用程序类：

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

这是我得到的错误：
