异常运行中的应用程序

Question

这是我的fx课

package application;
import java.io.File;
import java.net.URL;
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("as1.fxml"));


        primaryStage.setTitle("Abdul-Rahim University");
        primaryStage.setScene(new Scene(root, 800, 500));
        primaryStage.show();
    }


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

这是as1.fxml：
