Java 小白，实在不知道怎么做。求大侠解答！

public class Person {

Person father;

Person mother;

Gender gender;

Integer age;

List<Person> children;

int level = 0;

public enum Gender {

Male,

Female;

}

For the above class, you basically have to implement 2 methods.

public List<Person> getOldestSisters() (person can have multiple parents since remarrying )

public List<Person> getGreatestAncestors()

Find the oldest sisters of the given Person object. Such class recursively defines a Person father, Person mother, and a List<Person> of children

请问楼主这是哪个公司的面试题？
找最年长的姐姐我觉得就是通过父亲的children list和母亲的children list合在一起（有可能重新结婚所以list可能不一样），按照年龄排序，最大的那个就是了。
