Getting an element from a specific position from a ConcurrentLinkedDeque

Question

How can i get an element from a specific position from a ConcurrentLinkedDeque just like ArrayList.get(index) ?

Thanks and regards,

Rajesh.

ConcurrentLinkedDeque doesn't allow random access. you can only retrieve first or last element.

though you can iterate over it.

ConcurrentLinkedDeque<Integer> dq = new ConcurrentLinkedDeque<>();
Iterator<Integer> itr = dq.iterator();
while (itr.hasNext()) {
    Integer i = itr.next();
}
