Scheduling

lHow does the Java runtime schedules CPU time among threads?

–If a thread is blocked (I/O) or sleep, it uses no CPU time

–The runtime chooses the thread with the highest priority

–If all threads have the same priority (then order is not defined)

lPreempting threads (share processor)

lAllow one thread to run till it gives up the processor. All other threads will be starved of CPU time

lBecause of this, you should not perform long compute-bound tasks without calling Thread.yield() periodically
