Tell me: what is the difference between slapping someone in the face, and taking a nap? That is the difference between interrupt() and sleep(). They are completely different, not used for the same purpose, and have no relation except that one (taking a nap) can be affected if someone else does the other to you (slap in the face).
2. In which situation those are used being used?
You use interrupt() when you want to interrupt() another Thread which may be waiting on something. You use sleep() when you want this thread to pause for a bit.
