I am working currently on internalization functionality in my application.

I created bundle folder with 2 files, 2 languages available:

messages_pl.properties and messages_en.properties.

In my main fxml file (containing menuBar as well) I set internalization resource for each and every controls.

This piece of code works perfectly for me, I can switch from "en" to "pl"

public void start(Stage primaryStage) throws Exception {        

    Locale.setDefault(new Locale("en"));

    Pane borderPane = FxmlUtils.fxmlLoader(BORDER_PANE_MAIN_FXML);

    Scene scene = new Scene(borderPane);

    primaryStage.setScene(scene);

    primaryStage.setTitle(FxmlUtils.getResourceBundle().getString("tittle.application"));

    primaryStage.show();

The problem is that I don't want manipulate the code, switching from en to pl each time I need to change language.

I would like to have it dynamically, based if I choose RadioMenuItem "Polish" or RadioMenutItem "English".

Do you know how to adapt my source code consequently?

I found a solution, it is not the prettiest but it works:

Controller:

public class Controller implements Initializable {



    @FXML

    private MenuItem en;

    @FXML

    private MenuItem de;



    Runnable changeLanguage; // add setter



    @Override

    public void initialize(URL location, ResourceBundle resources) {

        en.setOnAction(event -> {

            Locale.setDefault(Locale.ENGLISH);

            reload();

        });

        de.setOnAction(event -> {

            Locale.setDefault(Locale.GERMAN);

            reload();

        });

    }

    private void reload() {

        changeLanguage.run();

    }

}

Main:

public class Main extends Application {



    private Stage primary;



    @Override

    public void start(Stage primaryStage) throws Exception {

        this.primary = primaryStage;

        load();

        primaryStage.show();

    }



    private void load() throws IOException {

        FXMLLoader loader = new FXMLLoader(getClass().getResource("View.fxml"));

        loader.setResources(ResourceBundle.getBundle("stackoverflow/language/language", Locale.getDefault())); // the main package is stackoverflow which contains language

        primary.setScene(new Scene(loader.load(), 400, 600));

        Controller controller = loader.getController();

        controller.changeLanguage = () -> {

            try {

                load();

            } catch (IOException e) {

                e.printStackTrace();

            }

        };

    }



    public static void main(String args) {

        Locale.setDefault(Locale.ENGLISH);

        launch(args);

    }



}

and View.fxml:

<?xml version="1.0" encoding="UTF-8"?>



<?import javafx.scene.layout.AnchorPane?>

<?import javafx.scene.control.MenuBar?>

<?import javafx.scene.control.Menu?>

<?import javafx.scene.control.MenuItem?>

<AnchorPane xmlns="http://javafx.com/javafx"

            xmlns:fx="http://javafx.com/fxml"

            fx:controller="stackoverflow.language.Controller">

    <MenuBar>

        <Menu text="%language">

            <MenuItem fx:id="en" text="%en"/>

            <MenuItem fx:id="de" text="%de"/>

        </Menu>

    </MenuBar>

</AnchorPane>

This is how the classes are:
