Observe that without the brackets over a, b, it would imply that you are trying to pass 3 arguments to processList method - a, b, and b->System.out.println(a*b), which is incorrect. You actually want to pass only two arguments - a and the lambda expression. Therefore, whenever the method of a functional interface takes more than one parameter, you need to put the arguments within brackets.

I believe this should be (changes in bold):
