What is an Daemon thread in Java?

• Daemon threads can shut down any time in between their flow, Non-Daemon i.e. user thread executes completely.
• Daemon threads are threads that run intermittently in the background as long as other non-daemon threads are running.
• When all of the non-daemon threads complete, daemon threads terminates automatically.
• Daemon threads are service providers for user threads running in the same process.
• The JVM does not care about daemon threads to complete when in Running state, not even finally block also let execute. JVM do give preference to non-daemon threads that is created by us.
• Daemon threads acts as services in Windows.
• The JVM stops the daemon threads when all user threads (in contrast to the daemon threads) are terminated. Hence daemon threads can be used to implement, for example, a monitoring functionality as the thread is stopped by the JVM as soon as all user threads have stopped.
