convert to lambda from rx java expression

Question

I've started to grok into retrolambda and rxjava. Some expressions i'v converted by myself, but some of them i can't convert. I've added retrolambda to my project.Here is examples

public Observable<ImmutableList<Repository>> getUsersRepositories() {
        return githubApiService.getUsersRepositories(user.login)
                .map(repositoryResponses -> {
                        final ImmutableList.Builder<Repository> listBuilder = ImmutableList.builder();
                        for (RepositoryResponse repositoryResponse : repositoryResponses) {
                            Repository repository = new Repository();
                            repository.id = repositoryResponse.id;
                            repository.name = repositoryResponse.name;
                            repository.url = repositoryResponse.url;
                            listBuilder.add(repository);
                        }
                        return listBuilder.build();
                })
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread());
    }

But i don't know how to convert this peace of code:

obs.subscribe(new Observer<List<Integer>>() {
        public void onCompleted() {
            System.out.println("completed");
        }

        public void onError(Throwable e) {
            System.out.println("failure");
        }

        public void onNext(List<Integer> value) {
            System.out.println("onnext=" + value);
        }
    });

Answer 1

I think that you want to make something like this:

obs.subscribe(
         (List<Integer> value) -> System.out.println("onnext=" + value),
         (Throwable e) -> System.out.println("failure"),
         ()-> System.out.println("completed"));

You can check this blog and this example in GitHub.
