Convert iterable to list using streams [duplicate]

Question

I have a simple loop that adds elements from one list to another list. How can the same result be achieved using streams?

List<User> users = new ArrayList<>();
for(User user: userRepository.findAll()) {
    users.add(user);
}

The reason for doing so is because userRepository.findAll() returns Iterable<User>

Answer 1

spliterator() converts Iterable in stream and then collect it as a List using collect()

List<User> users = 
  StreamSupport.stream(userRepository.findAll().spliterator(), false)
    .collect(Collectors.toList());
