yied() method

[Cristian Negresco]

Hi,
JQPlus question:test2/threads/q4
What is guaranteed by the JVM about the method yield()?

I have answered:
"The current thread will sleep for some time giving a chance to other threads to run."
The good answer:
"Nothing is guaranteed."
How that, in jdk1.2:yield
"public static void yield()
Causes the currently executing thread object to temporarily pause and allow other threads to execute."?
So no word about best-effort or something like that.
So how is it?
Thanks,
Cristian

Yes. Nothing is guaranteed
Reason being that, yield() will only yield if there are any threads that needs to be executed like a highpriority thread or so. Its not mandatory for the current thread to sleep and let the other threads to let run...since it(ie JVM) implementation specific

The following is a link to a search made in this forum for all threads about yield, that topic is heavily discussed here and information is made to be reused, so browse around and tell us if you did not find what you want.
