Not Predicate

With the static method Predicate.not() we can invert conditions. This is particular useful in combination with method references.

Since Java 11

import static java.util.function.Predicate.not; import java.util.List; public class NotPredicate { public static void main(String... args) { List.of("", "venus", " ", "mars", " ", "earth") // .stream() // .filter(not(String::isBlank)) // .forEach(System.out::println); } }
