Answer 1

We can also do the same using java 8.

public static List reverseList(List list) {
        List reverse = new ArrayList<>(list.size());

        list.stream()
                .collect(Collectors.toCollection(LinkedList::new))
                .descendingIterator()
                .forEachRemaining(reverse::add);

        return reverse;
    }
