//1.过滤list中的基本数据类型

List<String> result1 = lines.stream()
.filter(line -> !"mkyong".equals(line))
.collect(Collectors.toList());
result1.forEach(System.out::println);
//end:结果spring node
//2.过滤list<bean>中的数据
List<Student> stuList = new ArrayList<Student>();
Student s1 = new Student("222","zhangsan");
Student s2 = new Student("222","lisi");
Student s3 = new Student("212","wangwu");
stuList.add(s1);
stuList.add(s2);
stuList.add(s3);
List<Student> result2 = stuList.stream()
//根据两个属性进行过滤
.filter(s -> StringUtils.equals("222", s.getId()) && StringUtils.endsWith(s.getName(), "san"))
.collect(Collectors.toList());
result2.forEach(System.out::println);
//end:结果:Student [id=222 zhangsan]
}
}
使用java 8 进行过滤
