志向和热爱是伟大行为的双翼。——歌德
之前分享了vavr,今天在分享一个同类框架eclipse-collections
官方文档:http://www.eclipse.org/collections/

体验下,这是java8 Stream
的:

16 boolean anyPeopleHaveCats =
this.people
.stream()
.anyMatch(person -> person.hasPet(PetType.CAT));
long countPeopleWithCats =
this.people
.stream()
.filter(person -> person.hasPet(PetType.CAT))
.count();
List<Person> peopleWithCats =
this.people
.stream()
.filter(person -> person.hasPet(PetType.CAT))
.collect(Collectors.toList());
用eclipse-collections
:

this.people
.anySatisfy(person -> person.hasPet(PetType.CAT));
int countPeopleWithCats =
this.people
.count(person -> person.hasPet(PetType.CAT));
MutableList<Person> peopleWithCats =
this.people
.select(person -> person.hasPet(PetType.CAT));
简短了原本的代码
