Olá a todos. Copiei este código para depois estudá-lo. Mas não consigo fazer com que ele encontre o arquivo fxml. Estou usando Notepad++7.5.6 , JDK 1.8.

//Label label = new Label("Meu texto legar");
//Pane root = FXMLLoader.load(getClass().getResource("Layout2.fxml"));
/*FXMLLoader loader = new FXMLLoader();

FXMLLoader loader = new FXMLLoader();
String arquivo = "Layout2.fxml";
FileInputStream input = new FileInputStream(arquivo);
Pane root = (Pane) loader.load(input);
Scene scene = new Scene(root,850,400);
primaryStage.setScene(scene);
primaryStage.setTitle("Principal");
