Java implementation of the producer consumer Model (Implementation three)

Exchanger is a concurrency tool under the Java.util.concurrent class library. The following is a description of exchanger in the Java API documentation.

A synchronization point at which threads can pair and swap elements within pairs. Each thread presents some object in entry to the Exchange method, matches with a partner thread, and receives its partner ' S object on return. An Exchanger is viewed as a bidirectional form of a synchronousqueue. Exchangers May is useful in applications such as genetic algorithms and pipeline designs.

That is, exchanger must be accompanied by a pair of threads appearing.
