如何将hashmap $ ArrayList的条目转换为hashmap

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class HashMapArrayListConversion {
    public static void main(String[] args) {
        List<Object> list = new ArrayList<>();
        Map<String, Object> map1 = new HashMap<>();
        map1.put("key1", "value1");
        map1.put("key2", "value2");

        Map<String, Object> map2 = new HashMap<>();
        map2.put("key3", "value3");
        map2.put("key4", "value4");

        list.add(map1);
        list.add(map2);

        Map<String, Object> resultMap = new HashMap<>();
        convertListToMap(list, resultMap);

        System.out.println(resultMap);
    }

    private static void convertListToMap(List<Object> list, Map<String, Object> resultMap) {
        for (Object obj : list) {
            if (obj instanceof Map) {
                resultMap.putAll((Map<String, Object>) obj);
            } else if (obj instanceof List) {
                convertListToMap((List<Object>) obj, resultMap);
            } else {
                // Handle other types if needed
            }
        }
    }
}

{key1=value1, key2=value2, key3=value3, key4=value4}
