How do I randomly start activities?

I'm looking to randomly start activities in android studio without repetition. I'd like to be able to start an activity randomly by clicking a button and in an 'if' statement. Whoever can help out that would be fantastic! Thank you.

   ArrayList<Class> activities = new ArrayList<>();


  @Override
  public void onCreate(Bundle savedInstanceState) {
       //your codes...
       activities.add(History.class);
       activities.add(Bookmark.class);
       activities.add(Themes.class);  

       //your codes

   }



public void openActivity(Class class_) {
    Intent intent = new Intent(this, class_);
    startActivity(intent);
}

public void openRandomActivity(){

    Class that = activities.get(new Random().nextInt(activities.size()));

    activities.remove(that); // after using, remove from list

    openActivity(that);
}

Call openRandomActivity when a user click to button.
