java的List集合里面放了Map,List<Map<String,Object>>,如何判定人名相同,就组合成一个对象?

Question

之前的数据样例:
[
{
"name": "张三",
"公司": "腾讯"
},
{
"name": "李四",
"公司": "阿里"
},
{
"name": "王五",
"公司": "百度"
},
{
"name": "张三",
"地址": "四川"
},
{
"name": "李四",
"地址": "湖南"
},
{
"name": "王五",
"地址": "广东"
}
]

我需要的数据:
[
{
"name": "张三",
"公司": "腾讯",
"地址": "四川"
},
{
"name": "李四",
"公司": "阿里",
"地址": "湖南"
},
{
"name": "王五",
"公司": "百度",
"地址": "广东"
}
]

public static void main(String[] args) {

        List<Map<String, Object>> list = new ArrayList<>();
        Map<String, Object> objectMap = new HashMap<>();
        objectMap.put("name","张三");
        objectMap.put("公司","腾讯");
        Map<String, Object> objectMap1 = new HashMap<>();
        objectMap1.put("name","李四");
        objectMap1.put("公司","阿里");
        Map<String, Object> objectMap2 = new HashMap<>();
        objectMap2.put("name","王五");
        objectMap2.put("公司","百度");
        Map<String, Object> objectMap3 = new HashMap<>();
        objectMap3.put("name","王五");
        objectMap3.put("地址","北京");
        list.add(objectMap);
        list.add(objectMap1);
        list.add(objectMap2);
        list.add(objectMap3);
        Map<String, Map<String,Object>> map = new HashMap<>();
        list.forEach((s)->{
            if(map.containsKey(s.get("name"))){
                Map<String, Object> map1 = map.get(s.get("name"));
                map1.putAll(s);
            }else{
                Map<String, Object> newMap = new HashMap<>();
                newMap.putAll(s);
                map.put(s.get("name").toString(),newMap);
            }
        });
        map.forEach((k,v)->{
            System.out.println(k);
            v.forEach((e,a)->{
                System.out.println(e+":"+a);
            });

        });
    }
