Tool classes for threads (Exchange)

public class Exchanger<v>extends Object

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.

Instance:

Import Java.util.concurrent.Exchanger;
Import Java.util.concurrent.ExecutorService;
Import java.util.concurrent.Executors;
