Cyclicbarrier is a synchronous helper class, and the main function is to let a group of threads wait for each other, knowing that all arrive at a common barrier and walk together. In programs that involve a set of fixed-size threads, these threads have to wait for each other, and cyclicbarrier is useful at this time. Because the barrier can be reused after releasing the waiting thread, it is called a cyclic barrier.　　Cyclicbarrier support for Runnable
