Java Thread Synchronization helper class exchanger-interchange

The synchronization point of the thread that can pair and swap elements in pairs. Each thread renders a method on the entry to the exchange method, matches the partner thread, and receives the object of its partner when it returns. Exchanger may be considered as SynchronousQueue a bidirectional form. Exchanger may be useful in applications such as genetic algorithms and pipeline design.
