RxJava and parallel execution of observer code

Question

I am having the following code using RxJava Observable api :

Observable observable = fileProcessor.processFileObservable(processedFile.getAbsolut         


        

Answer 1

This still comes in the same sequence. Even on new threads

    Observable ob3 = Observable.range(1, 5);

    ob3.flatMap(new Func1>() {

        @Override
        public Observable call(Integer pArg0) {

            return Observable.just(pArg0);
        }

    }).subscribeOn(Schedulers.newThread()).map(new Func1() {

        @Override
        public Integer call(Integer pArg0) {

            try {
                Thread.sleep(1000 - (pArg0 * 100));
                System.out.println(pArg0 + "  ccc   " + Thread.currentThread().getName());
            } catch (Exception e) {
                e.printStackTrace();
            }

            return pArg0;
        }

    }).subscribe();

Output

1 ccc RxNewThreadScheduler-1

2 ccc RxNewThreadScheduler-1

3 ccc RxNewThreadScheduler-1

4 ccc RxNewThreadScheduler-1

5 ccc RxNewThreadScheduler-1
