mapToInt(HousingRecord::getCurrentHomeValueIndex).min() error

I try to use Stream.of(records) .mapToInt(HousingRecord::getCurrentHomeValueIndex) .min(); but my IDE shows an error "non-static method cannot be referenced from a static context". Why my method reference doesn`t work?

I resolved it myself :) I should have used records.stream(), not Stream.of(records) Because Stream.of gave me a stream with one element - collection itself, instead of creating a stream of records as .stream() does.
