 |

Hi there,
I've got a fundamental question which no tutorial was yet able to give
me an answer. Suppose I'd like to start a Java-App here on my machine
and give it a very low (maybe the lowest) thread-priority, that is,
setPriority(...).
Does it mean that this thread is heaving the lowest priority in my
SYSTEM or JUST in the JVM? In the latter case, the JVM would be
working as an ordinary process without having a lower priority than
other processes. In other words: Does Java (the JVM) work the same way
no matter how I set up the thread-priority?
Thanks for your response!

The answer is undefined. It depends completely on the behaviour of the
thread subsystem in the underlying OS (or JVM thread implementation).

i would be guessing, but i'd rekon it would be the jvm, as it manages
the java program running. and there would only be 1 instance of the jvm
running when u execute the java program within the o/s
