Any null safe alternative to ArrayList.addAll?

Question

I was refactoring some old code of mine that I\'ve written and I stumbeled on this code:

    List fullImagePool = new ArrayList<>();
           


        

Answer 1

Using Java 8:

List fullImagePool = Stream.of(style.getTestMH(), /* etc */)
                                         .filter(Objects::nonNull)
                                         .flatMap(l -> l.stream())
                                         .collect(Collectors.toList());
