Java Stream: divide into two lists by boolean predicate

Question

I have a list of employees. They have isActive boolean field. I would like to divide employees into two lists: activeEmployees

Answer 1

What is the most sophisticated way?

Java 12 of course with new Collectors::teeing

List> divided = employees.stream().collect(
      Collectors.teeing(
              Collectors.filtering(Employee::isActive, Collectors.toList()),
              Collectors.filtering(Predicate.not(Employee::isActive), Collectors.toList()),
              List::of
      ));

System.out.println(divided.get(0));  //active
System.out.println(divided.get(1));  //inactive
