SIngle RxJava how to extract object

Question

I can think of two ways to get the value from Single

Single<HotelResult> observableHotelResult = 
                            apiObservables.getHotelInfoObservable(requestBody);

final HotelResult[] hotelResults = new HotelResult[1];
    singleHotelResult
            .subscribe(hotelResult -> {
                hotelResults[0] = hotelResult;
            });

Or

    final HotelResult hotelResult = singleHotelResult
                                    .toBlocking()
                                    .value();

It's written in the documentation that we should avoid using .toBlocking method.

So is there any better way to get value

Answer 1

Even it is not recommended to block it (you should subscribe), in RxJava v2 the method for blocking is blockingGet(), it returns the object immediately.
