Answer
ArrayDeque is not thread-safe. Frame the concept in practical terms so you can explain it during interview discussion.
ArrayDeque is not synchronized, meaning it's not thread-safe for concurrent modifications. In a multi-threaded environment, using it for stack operations can lead to data inconsistency or corruption. To safely use it across multiple threads, external synchronization is required, or consider using thread-safe alternatives like ConcurrentLinkedDeque.
