Is java main method a thread? [duplicate]

Question

I was wondering if Java main method was a thread or not. I noticed that if the main method returns, all threads are killed. Can you explain me why this happens? Thank you in advance.

Answer 1

Actually the main method runs on the Main thread ! The main threads invokes your main()

All the other threads of a java application are spawned from this thread !

Answer 2

When you start your application the OS create a Thread for you which is the main thread (or UI thread in other contexts).

This thread just run your main method and stop. Anyway there are two types of threads.

• User thread
• Daemon threads

The main thread is a User thread. The JVM will be stopped when all user threads are finished.

Well, it's just a "fast response" i'm pretty use you can found better answer by experts here.
