What is difference between sleep() method and yield() method of multi threading?

Question

As currently executing thread while it encounters the call sleep() then thread moves immediately into sleeping stat. Whereas for yield() thread moves into runnable

Answer 1

Yield: It is a hint (not guaranteed) to the scheduler that you have done enough and that some other thread of same priority might run and use the CPU.

Thread.sleep();

Sleep: It blocks the execution of that particular thread for a given time.

TimeUnit.MILLISECONDS.sleep(1000);
