A thread could be interrupted even when it was not sleeping.

Why does the sleep() have to specifically handle this?

Why is run() itself not the right method to throw that exception asking us to declare/handle it?

run() can't throw it since then you couldn't catch it -- you don't call run(), the Thread class does.

Sleep() does this because calling interrupt() is a convenient way to tell a thread to shut down; throwing the exception gives your run() method a way to clean up before exiting.
