Java8 filter collect both type of value

Question

Is there a way to collect both filtered and not filtered value in java 8 filter ?

One way is:

.filter( foo -> {
    if(!foo.apply()){
   // add to required collection
    }
    return foo.apply();
  }

Is there a better alternative ?

Answer 1

 Map<Boolean, List<Foo>> map = 
     collection.stream().collect(Collectors.partitioningBy(foo -> foo.isBar());
