CyclicBarrier Example

CyclicBarrier is a very interesting functionality for Concurrency in Java. Here is a quick example which shows how this is implemented

1. Imagine a scenario where two doctors are needed to see a patient. One doctor has to wait while the other gets available.
2. So a doctor waits at a "Barrier" for the second doctor to come and only then do both proceed with the patient
3. And this need to be Cyclic in nature for all the patients in the hospital, i.e the Barrier needs to be Cyclic in nature
4. This is a simple example which showcases the "Cyclic" nature of the CyclicBarrier. For a detailed demo, you can refer to this page
