How to find the name of the parent thread?

Question

I know we can have \'parents\' and \'children\' when we are talking about processes. But is it possible to get parent Thread name?

No - there's no particular concept of a "parent" thread in either Java or .NET. As per the .NET answer you referenced, however, if you're creating the thread yourself you can always give a name which indicates the "creator" thread name within the new thread's name.

EDIT: Your sample code sets the name before it starts... but then overwrites it after it starts, ignoring the previous name.

I'd expect something like:

String currentName = Thread.currentThread.name();
Thread thread = new Thread(new RunnableC());
thread.setName("C (started by" + currentName + ")");
thread.start();

That would be the only place the name of the thread would be set.

Note that this also uses the idea of implementing Runnable rather than extending Thread. That's a separate matter, but is the preferred approach in most cases.
