问题 I have a class called Student and it has two fields grade and school . Both of two fields need to be fetched from remote server. When two result returned, I new a Student object. With help of RxJava , I have done it in two ways, one in flatMap and another in zip operator. Observable<String> gradeObservable = Observable.create((ObservableOnSubscribe<String>) emitter -> { Thread.sleep(1000); emitter.onNext("senior"); }).subscribeOn(Schedulers.io()); Observable<String> schoolObservable =
