Daemon threads are low priority background threads which provide services to user threads. It’s life depends on user threads. If no user thread is running then JVM can exit even if daemon threads are running. JVM do not wait for daemon threads to finish. Daemon threads perform background tasks such as garbage collection, finalizer etc. The only purpose of daemon thread is to serve user thread so if there are no user threads, there is no point of JVM to run these threads, that’s why JVM exits once there are no user threads. Two method related to daemon thread Public void setDaemon(boolean status) : This method can be used to mark thread as user or daemon thread. If you put setDaemon(true), it makes thread as daemon.
