I have not seen author setting thread ID anywhere. Where it is getting set.
i see output as below
RunnableJob is being run by thread1 (9)
RunnableJob is being run by Thread-1 (11)
Main thread: main(1)
RunnableJob is being run by thread2 (10)
which line is printing below output
RunnableJob is being run by Thread-1 (11)
please advise
Any links resources ideas highly appreciated. Thanks in advance

It's thread3, with the default thread name. The Javadocs for the Thread class mention that:
The end of the tutorial you linked mentions that "Thread-1" is the default name, too.
If a name is not specified when a thread is created, a new name is generated for it.

Specifically it's being set here in the constructor for Thread:
/**
* Allocates a new {@code Thread} object. This constructor has the same
* effect as {@linkplain #Thread(ThreadGroup,Runnab
* {@code (null, null, gname)}, where {@code gname} is a newly generated
* name. Automatically generated names are of the form
* {@code "Thread-"+}<i>n</i>, where <i>n</i> is an integer.
*/
public Thread() {
init(null, null, "Thread-" + nextThreadNum(), 0);
}

I see main thread and thread1 and thread2 in the code. Where from default thread is coming in this example.
Specifically it's being set here in the constructor for Thread:
How to check which specific constructor it is setting from
Please advise
which is Default thread?
When I said "default thread name," I meant "the name that is assigned to threads, by default." There is no such thing as a "default thread."

Default thread is below thread in the code right?
Please advise
Thread thread3 = new Thread(runnableJob);
thread3.start();
Please advise
