clarification on the concept of Java thread

Question

which is the thread that will begin as soon as the execution of a java program begins? This was asked in an interview for me. so can anyone suggest the answer here

Answer 1

From Thread API document

When a Java Virtual Machine starts up, there is usually a single non-daemon thread (which typically calls the method named main of some designated class).

And this thread will be called as main thread.

Answer 2

The thread which is created when you start is called the main thread. It is the one which invokes the main method.

Edit: apparently someone beat me to the answer.
