Take all MenuItems, filter selected and map them to String.

MenuButton mb = new MenuButton();
mb.getItems().addAll(new CheckMenuItem("One"), new CheckMenuItem("Two"), new CheckMenuItem("Three"));
mb.getItems().stream().forEach((MenuItem menuItem) -> menuItem.setOnAction(ev -> {
    final List<String> selectedItems = mb.getItems().stream()
            .filter(item -> CheckMenuItem.class.isInstance(item) && CheckMenuItem.class.cast(item).isSelected())
            .map(MenuItem::getText)
            .collect(Collectors.toList());
    System.out.println(selectedItems);
}));
