Convert observable to list

Question

I am using RxJava.

I have an Observable<T>. How do I convert it to List<T>?

Seems to be a simple operation, but I couldn't find it anywhere on the net.

You can use toList() or toSortedList() . For e.g.

observable.toList(myObservable)
          .subscribe({ myListOfSomething -> do something useful with the list });
