Parameter
|

|---|---|---|
Reuse
|
It can not be reused once count reaches 0
|
It can be reinitialized once parties reaches to 0, so it can reused

|
It calls await() method to reduce the counter.
|
Common Event
|
It can not trigger common event when count reaches 0
|
It can trigger common event (Runnable) once reaches to a barrier point. Constructor:CyclicBarrier(int parties, Runnable barrierAction)
