Java基础篇之java8新特性：Stream之filter

1.前言

1）、filter的应用场景比较多

2.例子

public class Java8Filter {


    public static void main(String[] args) {

        List<String> list = Arrays.asList("aa","ddd");

        list = list.stream().filter(item->item.length() > 2).collect(Collectors.toList());

        System.out.println(list);

    }

}
