Example 1 with GroupedObservable

use of io.reactivex.observables.GroupedObservable in project RxJavaInAction by fengzhizi715.

the class RoundRobinForParallel2 method main.

public static void main(String[] args) {
    final AtomicInteger batch = new AtomicInteger(0);
    int threadNum = 5;
    final ExecutorService executor = Executors.newFixedThreadPool(threadNum);
    final Scheduler scheduler = Schedulers.from(executor);
    Observable.range(1, 100).groupBy(new Function<Integer, Integer>() {

        @Override
        public Integer apply(@NonNull Integer integer) throws Exception {
            return batch.getAndIncrement() % threadNum;
        }
    }).flatMap(new Function<GroupedObservable<Integer, Integer>, ObservableSource<?>>() {

        @Override
        public ObservableSource<?> apply(@NonNull GroupedObservable<Integer, Integer> integerIntegerGroupedObservable) throws Exception {
            return integerIntegerGroupedObservable.observeOn(scheduler).map(new Function<Integer, String>() {

                @Override
