Answer the following statements true (T) or false (F)
1. A thread is not runnable if it has terminated. 2. Some operating systems use timeslicing with threads. Therefore, they can enable threads to preempt threads of the same priority. 3. When the thread’s quantum expires, the thread returns to the running state as the op- erating system assigns it to a processor. 4. On a single-processor system without timeslicing, each thread in a set of equal-priority threads (with no other threads present) runs to completion before other threads of equal priority get a chance to execute 5. To determine the difference between two Instants, use class Duration’s static method difference, which returns a Duration object containing the time difference.
