Are Thread.sleep(0) and Thread.yield() statements equivalent?

Question

Are these two statement equivalent?

Thread.sleep(0);
Thread.yield();

Answer 1

No, they are not equivalent and besides the explanations above, I think it's necessary to check the Javadoc of yield. It seems not a good idea to use yield unless below situation meets.

 It is rarely appropriate to use this method. It may be useful
 for debugging or testing purposes, where it may help to reproduce
 bugs due to race conditions. It may also be useful when designing
 concurrency control constructs such as the ones in the
 {@link java.util.concurrent.locks} package.
