Sybex Typo Java 8 OCP Online Bonus Question 136/180 Mock 3

import java.util.concurrent.*;
import java.util.stream.*;
public class PrintHolidays {
   public static void main(String[] args) {
      ExecutorService service = Executors.newScheduledThreadPool(10);
      LongStream.of(101,704,1126) // p1
         .forEach(() -˃ service.submit( // p2
               c -˃ System.out.println(2+c))); // p3
      service.submit(() -˃ System.out.println("Happy Holidays!")); // p4
   }
}

Typo in explanation
"The forEach() method takes a Consumer<T>, so the lambda should have a generic argument on the left side on line p2; "

It should be  "The forEach() method takes a LongConsumer instead of Consumer<T>"
