FinalF.java

package finalf;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.stage.Stage;


public class FinalF extends Application {

    @FXML
    private Button button;

    @FXML
    private Label label;

    @FXML
    void handleButtonAction(ActionEvent event){


    }

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));

        Scene scene = new Scene(root);

        stage.setScene(scene);
        stage.show();
    }


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

}

let's try

in FXMLDocumentController.java, change the first line in loadSplashScreen() method,

from

StackPane pane = FXMLLoader.load(getClass().getResource("/SplashFXML.fxml"));

StackPane pane = FXMLLoader.load(getClass().getResource("SplashFXML.fxml"));

in FXMLDocument.fxml, add fx:id="root" to the AnchorPane section. make it change

from

AnchorPane id="AnchorPane" prefHeight="462.0" prefWidth="473.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.101" fx:controller="finalf.FXMLDocumentController"

AnchorPane id="AnchorPane" fx:id="root" prefHeight="462.0" prefWidth="473.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.101" fx:controller="finalf.FXMLDocumentController"

Hope it solves your problem after this two steps.
