As you can see from the output each thread is yielding the CPU when value of i is 1 giving another thread chance to execute.

Any other thread with reference to the thread currently sleeping say t can interrupt it calling t.

It has to wait for the Thread Scheduler to schedule it for its time slice. This transition of state takes place only if there is some other thread of same priority in Runnable state. Hence the no guarantee that the thread will stop execution as the criteria of another same priority thread might not be met.

Note: both Thread. Improve this answer. DarkDust DarkDust DarlDust: do the threads return to different waiting pools after calling these methods? No, they are not the same. Now if your thread wakes up and notices there's no important work to do right now, it can tell the scheduler "Let someone else do some work now" through yield.

Sleep wouldn't work, as the caller would need to know exactly how long one scheduling slot is and how much time it has left of that slot or when it would get scheduled next. In other words: with sleep, the caller would need to know implementation details of the scheduler, but not with yield. Junca, to be honest I have not seen real uses of Thread.

Wednesday, July 14, Difference between yield and sleep in Java Thread? Sleep vs yield in Java. Sleep and yield are two methods that are used to get CPU back from Thread to Thread Scheduler in java but they are completely different than each other. The major difference between Sleep vs yield is that sleep is more reliable than yield and it's advised to use sleep 1 instead of yield to relinquish CPU in multi-threaded Java applications to give an opportunity to other threads to execute.

In this Java tutorial, we will what are the differences between yield and sleep in Java.
