Java concurrency: Countdown latch vs Cyclic barrier

Question

I was reading through the java.util.concurrent API, and found that

• CountDownLatch: A synchronization aid that allows one or more threads to wait

Answer 1

One obvious difference is, only N threads can await on a CyclicBarrier of N to be release in one cycle. But unlimited number of threads can await on a CountDownLatch of N. The count down decrement can be done by one thread N times or N threads one time each or combinations.
