Java8，如何在Collectors.toMap()中添加过滤和映射

import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] args) {
        List<Person> persons = List.of(
                new Person("John", 25),
                new Person("Jane", 30),
                new Person("Alice", 20),
                new Person("Bob", 35)
        );

        Map<String, Integer> filteredAndMappedMap = persons.stream()
                .filter(person -> person.getAge() > 25) // 过滤年龄大于25的人
                .map(person -> Map.entry(person.getName(), person.getAge())) // 映射为键值对
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue)); // 收集到Map中

        System.out.println(filteredAndMappedMap);
    }

    static class Person {
        private String name;
        private int age;

        public Person(String name, int age) {
            this.name = name;
            this.age = age;
        }

        public String getName() {
            return name;
        }

        public int getAge() {
            return age;
        }
    }
}
