For a Stream<Integer>, findFirst() returns an Optional<Integer>. That means that ifPresent() takes a Consumer<Integer>, but you gave it a Consumer<Optional<Integer>>. Your lambda expression should take an Integer argument, not an Optional.

After you get it to compile, your program still won't print anything because you told it it print the first even number in the list, but your list only contains an odd number.
