我正在努力比较多个列表中的键/值，可能需要一些帮助。给定一个People的列表，它有一个firstName和age属性，以及一个单独的年龄列表，我如何过滤People列表以只返回那些具有其中一个匹配年龄的列表？

public class Main {
    public static void main(String[] args) {

        Person p1 = new Person("John", 25);
        Person p2 = new Person("Lisa", 54);
        Person p3 = new Person("Mike", 61);
        List<Person> people = new ArrayList<Person>();
        people.add(p1);
        people.add(p2);
        people.add(p3);

        List<Integer> ages = Arrays.asList(25, 54);
        List<Person> specificAges = people.stream().filter(p -> p.age == ages?????)

        System.out.println(specificAges);
    }
}

public class Person {
    private String firstName;
    private Integer age;

    public Person(String firstName, Integer age) {
        this.firstName = firstName;
        this.age = age;
    }

    @Override
    public String toString() {
        return firstName + " " + age;
    }
}

预期结果：["John 25", "Lisa 54"]
