The simplest route would be to create a new ArrayList from the Deque and sublist that.

public void test() {
    ArrayDeque<String> ad = new ArrayDeque<>();
    ad.add("Hello");
    ad.add("Bye!");
    ArrayList<String> al = new ArrayList<>(ad);
    List<String> alp = al.subList(1, al.size());
    System.out.println("ad=" + ad);
    System.out.println("al=" + al);
    System.out.println("alp=" + alp);
}

Note, however, that the ArrayList is a copy of the state of the Deque at the time and does not reflect changes in the Deque. If that is unacceptable then there are otrher (less simple) options.
