Массив строк Realm в Android

Почему да, конечно есть

public class Station extends RealmObject {
    private String name;

    // ... Generated getters and setters ...
}

а также

// field variable
RealmResults<Station> stations;
// field variable
RealmChangeListener<RealmResults<Station>> changeListener = new RealmChangeListener<RealmResults<Station>>() {
    @Override
    public void onChange(RealmResults<Station> results) {
        // handle onSuccess()
    }
}

а также

stations = realm.where(Station.class).findAll();
stations.addChangeListener(changeListener);

realm.executeTransactionAsync(new Realm.Transaction() {
   @Override
   public void execute(Realm realm) {
      Station station = new Station();
      for(String stationName : listOfStationNames) {
          station.setName(stationName);
          realm.insert(station);
      }
   }
});
