When should I use SynchronousQueue

Question

new SynchronousQueue()
new LinkedBlockingQueue(1)

What is the difference? When I should use SynchronousQueue against LinkedBlock

Answer 1

One reason to use SynchronousQueue is to improve application performance. If you must have a hand-off between threads, you will need some synchronization object. If you can satisfy the conditions required for its use, SynchronousQueue is the fastest synchronization object I have found. Others agree.
