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

Hi Jim,
Have you thought of introducing something like:
static <T> Predicate<T> Predicate.of(Predicate<T> 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,

Introduce a new static method Predicate::not which will allow
developers to negate predicate lambdas trivially.
