This one of this question which I don't know how to treat.

I think about this anwser: "1 new thread is created by the program."

Is not it true that when we run an application using main method at least one thread is created?

Actually, the JVM may several threads such as a main threads and a GC thread but the given program code itself just creates one.

I find this one a but confusingly worded.

in which case, option 4 should be correct.

Or, should I think that the program == main thread, and the program ie the main thread, creates no further threads?

Seems I could argue either way.

Questions asked in the OCPJP 6 are not as clear and unambiguous as Java 7 and later. So if you are taking OCPJP 6, you should try not to read too much into the question. Use the simplest of interpretations.
