如何排序值arraylist<hashmap<string，string>>

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;

public class Main {
    public static void main(String[] args) {
        // 创建一个示例的ArrayList<HashMap<String, String>>
        ArrayList<HashMap<String, String>> list = new ArrayList<>();
        HashMap<String, String> map1 = new HashMap<>();
        map1.put("name", "John");
        map1.put("age", "25");
        list.add(map1);

        HashMap<String, String> map2 = new HashMap<>();
        map2.put("name", "Alice");
        map2.put("age", "30");
        list.add(map2);

        // 提取HashMap，保存到新的列表中
        ArrayList<HashMap<String, String>> extractedList = new ArrayList<>();
        for (HashMap<String, String> map : list) {
            extractedList.add(map);
        }

        // 创建自定义比较器
        Comparator<HashMap<String, String>> comparator = new Comparator<HashMap<String, String>>() {
            @Override
            public int compare(HashMap<String, String> map1, HashMap<String, String> map2) {
                // 根据name键进行比较
                String name1 = map1.get("name");
                String name2 = map2.get("name");
                return name1.compareTo(name2);
            }
        };

        // 对提取的列表进行排序
        Collections.sort(extractedList, comparator);

        // 将排序后的列表重新放入原始的ArrayList
        list.clear();
        for (HashMap<String, String> map : extractedList) {
            list.add(map);
        }

        // 打印排序后的结果
        for (HashMap<String, String> map : list) {
            System.out.println(map);
        }
    }
}
