User and Daemon are basically two types of thread used in Java by using a ‘Thread Class’.
User Thread (Non-Daemon Thread) : In Java, user threads have a specific life cycle and its life is independent of any other thread. JVM (Java Virtual Machine) waits for any of the user threads to complete its tasks before terminating it. When user threads are finished, JVM terminates the whole program along with associated daemon threads.
Daemon Thread : In Java, daemon threads are basically referred to as a service provider that provides services and support to user threads. There are basically two methods available in thread class for daemon thread: setDaemon() and isDaemon().
