True or False: CountDownLatch count can be reset.

  1. True

  2. False

The correct answer is: False

A CountDownLatch count cannot be reset once it has reached zero. This is because once the count has reached zero, the latch is released and can no longer be used. This is why it is important to carefully initialize the count in a CountDownLatch object to achieve the desired synchronization. So while it is true that the count can be decreased through the use of the countDown() method, it cannot be reset back to its original value.
