Question

 String image = JavaFXApplication9.class.getResource("splash.jpg").toExternalForm();
      root.setStyle(" -fx-background-image: url('" + image + "'); 
               -fx-background-position: center center; 
               -fx-background-repeat: stretch;");

Can anyone help me figure this out? :S I’ve tried a lot.

I know it’s a small error.

Try to clean and re-build the project.
EDIT:
Edit your start method according to this working one:

@Override
public void start(Stage primaryStage) {
    StackPane root = new StackPane();
    String image = this.getClass().getResource("splash.jpg").toExternalForm();
    root.setStyle(" -fx-background-image: url('" + image + "');  "
            + "-fx-background-position: center center; "
            + "-fx-background-repeat: stretch;");
    primaryStage.setScene(new Scene(root, 300, 250));
    primaryStage.show();
}

Be sure that the splash.jpg image file is in the same package of your main class.
