use a CountDownLatch multiple times

Question

Is there any way to use a unique CountDownLatch multiple times?

I mean after creating an instance of CountDownLatch and set it's count value, after it reaches 0 by invoking countDown() method on that instance, we set a new count value and again start to count down on that instance or when a CountDownLatch reaches 0, it will set it's count value automatically to the value that we determine in it's constructor.

No.

Use CyclicBarrier instead, which supports reset.

there isn't any way by using just countDownLatch? – mohamadreza Nov 30 '19 at 08:27
No. You need to custom a reset method. Here is a reset-able version. https://stackoverflow.com/questions/6595835/resettable-countdownlatch – xingbin Nov 30 '19 at 08:30
