import java.net.URL;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        URL url = new File("src/main/java/sample/sample.fxml").toURI().toURL();
        Parent root = FXMLLoader.load(url);
        primaryStage.setTitle("Hello World");
        primaryStage.setResizable(false);
        primaryStage.setScene(new Scene(root, 600, 400));

    <Button fx:id="btn_click_me" mnemonicParsing="false" onAction="#btnClickMeOnAction" text="Click Me" />
    <Label fx:id="lblInfo" />
</FlowPane>
