How to know the cause of InterruptedException in Java

Question

How to know the thread A that interrupted the thread B that is throwing the InterruptedException?

Answer 1

No, you could not know which thread triggers the interrupt.

It is kind of status flag, that's it. No matter InterruptedException or isInterrupted(), there is no extra information provided.

Further, if you need to cooperate threads in finer grade, try other ways.
