Bruce,
When I read your chapter on Concurrent Programming,In the section of Parallel Streams, For the isPrime() method in ParallelPrime.java, I tried to use (long) Math.sqrt(n) but the compiler gives an error，When I write the cast of (int) Math.sqrt(n) like this, it does not report an error ，I think this is a code error, because the parameter of the source code is int primetive type.
Please have a look.
My java version is "17.0.1" 2021-10-19 LTS
