I think the code should be `Integer comparisonCode = 1;` for option 3 to not change the meaning of the code.

Hello,

I think the code should make usage of comparisonCode instead of .filter(a->a == 0) ?

For example:

Code: Select all

        long l = courses.stream().peek(Course::printPassPercent)
                .map(c -> testCategory.compareToIgnoreCase(c.getCategory()))
                .filter(a -> comparisonCode.equals(a))
                .count();

So in this way we can answer that we can replace a -> comparisonCode.equals(a) with method reference comparisonCode::equals

Yes, that would be better.
