 URL fxmlURL = getClass().getResource("MyFile.fxml");
 Parent root = FXMLLoader.load(fxmlURL);

 // FXML file in a subpackage called `fxml`:
 URL fxmlURL2 = getClass().getResource("fxml/MyFile.fxml");
 Parent root2 = FXMLLoader.load(fxmlURL2);

 URL imageURL = getClass().getResource("myimages/image.png");
 Image image = new Image(imageURL.toExternalForm());
