The book didn't give an example program, so I only hope this is what it was looking for, but maybe there's a much better way to do it or way to improve how I'm doing it. For multiple threads, it’s recommended to use ThreadLocalRandom.Random is thread safe, but if multiple threads use the same instance of Random, it leads high contention (multiple threads to keep accessing the same “random” generator method) and it kills performance.
