CyclicBarrier

CyclicBarrier — A reusable Java synchronization barrier that releases a fixed group of threads when all parties reach the same phase boundary.

Concurrency Context

Unlike CountDownLatch, it can be reused across cycles. Failure semantics matter: interruption, timeout, or a failed barrier action can break the barrier for every participant, so production code must handle BrokenBarrierException explicitly.
