  • Imagine if the main thread were a daemon thread; it would start up, there would immediately be no non-daemon threads so the process would be terminated. Doesn't sound very useful, does it? You can emulate the same behaviour with an empty `main()` method if you want to. – Kayaman Dec 23 '15 at 07:24

Wrong. The JVM terminates when all threads running in it are daemon threads. Making main thread a daemon thread would do no good.

Typically, daemon threads are used to do clean-up tasks i.e, the tasks that can be stopped (unlike the core / important part of your app) without affecting the app too much.
