Answer 1

If what you need is simply List to List without manipulating result of List.

The cleanest version is:

List a = ... // ["1", "2", ..]
List b = Observable.from(a)
                      .map(a -> new B(a))
                      .toList()
                      .toBlocking()
                      .single();
