What method is used for non-blocking file lock acquisition?

  1. lock()

  2. tryLock()

  3. unlock()

  4. release()

The correct answer is: tryLock()

TryLock() is used for non-blocking file lock acquisition. This method tries to acquire a lock on a file and returns a boolean value indicating whether it was successful or not. It does not block the thread and allows it to continue executing if the lock could not be acquired. Lock() is a blocking method and will cause the thread to wait until the lock is acquired. Unlock() and release() are used to release a lock that has already been acquired and do not have anything to do with non-blocking file lock acquisition.
