Threads
class SimpleThreadFactory
implement Thread newThread(Runnable target)
Create and return a new thread with the target Runnable parameter you are passed.
Do *NOT* start this thread.
Certainly, do *NOT* run this thread.
Do not pass Go. Do not collect $200.
To repeat: just create a new Thread with the target Runnable and return it.
TAgeSum
implement int sumUpperLowerSplit(int[] ages, ThreadFactory threadFactory)
You will need use the passed in ThreadFactory to create a new thread or two (at your preference), start any threads you create, and join them.
Think about where you need to start and join them to ensure both correctness and an appropriate amount of parallelism.
