Actually it would be:
Predicate.of(String::isEmpty).negate()But
not(String::isEmpty) reads almost like !str.isEmpty()-Sundar

Hi Jim,
Have you thought of introducing something like: static Predicate Predicate.of(Predicate target) { return target; } instead? I think that might allow you to do things like:
Stream.of("", "A", "b", "c") .filter(Predicate.of(String::isEmpty).not()) .filter(Predicate.of("a"::equalsIgnoreCase).or("b"::equalsIgnoreCase)) .count(); best regards, -- daniel On 18/05/2018 17:35, Jim Laskey wrote: Introduce a new static method Predicate::not which will allow developers to negate predicate lambdas trivially.
