Question: 1 / 510

How do you check if a thread is a daemon?

isDaemon()

The isDaemon() method is used to check if a thread is a daemon thread. Daemon threads are background threads that run continuously without blocking the program from exiting. Therefore, options B and C are incorrect because they are not related to daemon threads. Option D is incorrect because it is a generic method used to check if a thread is currently running, but it does not specifically check for daemon threads.
