Java – math. In lambda expressions toIntExact？

I'm learning lambda expressions

I did this:

final static List<String> friends = Arrays.asList("Brian","Nate","Neal","Raju","Sara","Scott");

public static int countFriendsStartWithN() {
    return  Math.toIntExact(friends
            .stream()
            .filter(name -> name.startsWith("N"))
            .count());
}

The call to the count method returns a primitive long, but I want an int. I use math Tointexact takes the long value as int

Can I get int values directly in lambda expressions?

Solution

No, you cannot fit the call to tointexact to your method call chain, the flow pipeline This is because count is a terminal operation and returns a long primitive on which there is no method call Terminal operation is the operation that ends the flow pipeline and produces results (or side effects)

So I believe the best thing you can do is put up with the existing code With all due respect, it doesn't matter
