How do I display all country list in ComboBox? [JavaFX]

Question

public void start(final Stage frame) throws Exception {
    String[] locales = Locale.getISOCountries();
    for (String countrylist : locales) {
        Locale obj = new Locale("", countrylist);
        String[] city = {obj.getDisplayCountry()};
        for (int x = 0; x < city.length; x++) {
            cities = FXCollections.observableArrayList(obj.getDisplayCountry());
            country = new ComboBox<String>(cities);
        }
    }
}

I want to display the country list using Locale class. However I only manage to display one country in the Combobox when I run the code. I am not sure whether I got the loop wrong or what.

Use This code

  public void start(Stage primaryStage) throws Exception {

                ObservableList<String> cities = FXCollections.observableArrayList();
                ComboBox<String> country = new ComboBox<String>(cities);

                String[] locales1 = Locale.getISOCountries();
                for (String countrylist : locales1) {
                    Locale obj = new Locale("", countrylist);
                    String[] city = { obj.getDisplayCountry() };
                    for (int x = 0; x < city.length; x++) {
                        cities.add(obj.getDisplayCountry());
                    }
                }
                country.setItems(cities);
 }
