Java8.从一个list中获取某一元素集合

@Data
public class Person {
    private String name;
    private String age;
    
}

   List<Person> list = new ArrayList<>();
        Person person = new Person();
        person.setName("1");
        person.setAge(10);
        list.add(person);
        Person person1 = new Person();
        person1.setName("1");
        person1.setAge(10);
        list.add(person);
//获取person里面所有年龄集合
        List<String> ageList = list.stream().map(Person::getAge).collect(Collectors.toList());
