Loop through Observable's List of objects without using subscribe












0















I have an Observable object as follows



Observable<List<User>> observableUser = object.someMthodReturningObservable();


I want to loop though the observableUser, so I figured following code



1st Way:



observableUser.map(object ->{
List<User> list = object;
for(User user: list){
Employee employee= new Employee();
employee.setName(user.getName());
}
return null;
});


2nd Way:



observableUser.flatMap(Observable::from).subscribe(object -> {
User user = (User)object;
Employee employee= new Employee();
employee.setName(user.getName());
});


Is there any way to loop through the List without using subscribe and for loop i.e using only flatMap or map functionalities

  • do operations inside flatMap. user.flatMap(observableList -> observableList.flatMap(....
