Yield relinquish the CPU but sleep does not.
Sleep takes sleep time as input.

[Lave]: Yield relinquish the CPU but sleep does not.
Where did you get this idea? That's not even remotely true. Either method may relinquish the CPU, while neither is required to. The sleep() method is more likely to relinquish the CPU, because it generally has a minimum time span during which it cannot resume control of the CPU. Unless you're calling sleep(0), which is generally equivalent to yield().

In one of my java projects it happend, the sleep was consuming CPU continuosly, so I used yield along with sleep to get rid of this problem.
