No; but one was planned in the near past :-)
ConcurrentLinkedDeque was put together as a candidate
for Java6. You can find it from the "jsr166x" links at
including source at
This is reasonably well tested etc. The main reason for
deciding not to release is that its performance on
plain queue operations is not as good as others
like ConcurrentLinkedQueue so you'd only want to use it
when you need full Deque capabilities,
which is not common enough to justify inclusion in JDK.
But do please use it!
