    Java Streams with better efficiency:

      
Deque<Integer> deque = new ArrayDeque<>(a);

IntStream.rangeClosed(1, k).forEach(value -> {
    Integer last = deque.pollLast();
    deque.addFirst(last);
});

List<Integer> dequeList = new ArrayList<>(deque);

return queries.stream()
        .map(dequeList::get)
        .collect(Collectors.toList());
