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 state   ready state

User · Answer

yield    yield method is used to pause the execution of currently running process so that other waiting thread with the same priority will get CPU to execute Threads with lower priority will not be executed on yield  if there is no waiting thread then this thread will start its execution   join    join method stops currently executing thread and wait for another to complete on which in calls the join method after that it will resume its own execution   For detailed explanation  see this link

sleep   causes the thread to definitely stop executing for a given amount of time  if no other thread or process needs to be run  the CPU will be idle  and probably enter a power saving mode    yield   basically means that the thread is not doing anything particularly important and if any other threads or processes need to be run  they should  Otherwise  the current thread will continue to run

Sleep causes thread to suspend itself for x milliseconds while yield suspends the thread and immediately moves it to the ready queue  the queue which the CPU uses to run threads

Yield     method will stop the currently executing thread and give a chance to another thread of same priority which are waiting in queue  If thier is no thread then current thread will continue to execute  CPU will never be in ideal state  Sleep    method will stop the thread for particular time  time will be given in milisecond   If this is single thread which is running then CPU will be in ideal state at that period of time  Both are static menthod

Yield   will make thread to wait for the currently executing thread and the thread which has called yield   will attaches itself at the end of the thread execution  The thread which call yield   will be in Blocked state till its turn   Sleep   will cause the thread to sleep in sleep mode for span of time mentioned in arguments    Join   t1 and t2 are two threads   t2 join   is called then t1 enters into wait state until t2 completes execution  Then t1 will into runnable state then our specialist JVM thread scheduler will pick t1 based on criteria s

Both methods are used to prevent thread execution  But specifically  sleep    purpose if a thread don t want to perform any operation for particular amount of time then we should go for sleep   for e x  slide show   yield    purpose if a thread wants to pause it s execution to give chance of execution to another waiting threads of same priority thread which requires more execution time should call yield   in between execution  Note some platform may not provide proper support for yield     because underlying system may not provide support for preemptive scheduling moreover yield   is native method

One way to request the current thread to relinquish CPU so that other threads can get a chance to execute is to use yield in Java   yield is a static method  It doesn t say which other thread will get the CPU  It is possible for the same thread to get back the CPU and start its execution again   public class Solution9     public static void main String   args            yclass yy   new yclass             Thread t1  new Thread yy           t1 start            for  int i   0  i  lt 3  i                  Thread yield                System out println  during yield control   gt      Thread currentThread   getName                        class yclass implements Runnable        Override     public void run             for  int i   0  i  lt  3  i                  System out println  control   gt      Thread currentThread   getName

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

We can prevent a thread from execution by using any of the 3 methods of Thread class   yield   method pauses the currently executing thread temporarily for giving a chance to the remaining waiting threads of the same priority or higher priority to execute  If there is no waiting thread or all the waiting threads have a lower priority then the same thread will continue its execution  The yielded thread when it will get the chance for execution is decided by the thread scheduler whose behavior is vendor dependent   join   If any executing thread t1 calls join   on t2  i e  t2 join    immediately t1 will enter into waiting state until t2 completes its execution   sleep   Based on our requirement we can make a thread to be in sleeping state for a specified period of time  hope not much explanation required for our favorite method

Sleep   causes the currently executing thread to sleep  temporarily cease execution   Yield   causes the currently executing thread object to temporarily pause and allow other threads to execute   Read  this   Link Removed  for a good explanation of the topic
