Use of CyclicBarrier in java concurrency

Introduction CyclicBarrier is a thread-safe component introduced in java 5. It has the concept of a barrier, which is used to wait for all threads to finish executing before performing a specific operation. If we have many threads and each thread computes some data, then we need to wait for all the threads to finish executing and then add up the data computed by each thread to the final result, then we can use CyclicBarrier.
