{quote}
Resizable-array implementation of the Deque interface. Array deques have no
capacity restrictions; they grow as necessary to support usage. They are not
thread-safe; in the absence of external synchronization, they do not support
concurrent access by multiple threads. Null elements are prohibited. This class
is likely to be faster than Stack when used as a stack, and *faster than
LinkedList when used as a queue.*
