list<map>类型数据去重

未去重前的数据类型chooseList：

[
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":0,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":0,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":0,
        "id":34964
    },
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":0,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":1,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":0,
        "id":34964
    },
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":1,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":0,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":1,
        "id":34964
    },
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":1,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":1,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":1,
        "id":34964
    }
]

想得到的数据类型chooseList3：

[
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":1,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":1,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":1,
        "id":34964
    }
]

实现步骤：

1.获取唯一的name对应的json：

通过：

for  ( int  i  =   0 ; i  <  chooseList.size()  -   1 ; i ++ )  {
    for  ( int  j  =  chooseList.size()  -   1 ; j  >  i; j -- )  {
        if  (chooseList.get(j).get("name").equals(chooseList.get(i).get("name")))  {
            chooseList.remove(j);

        }
    }
}
得到：
[
    {
        "englishName":"lyss",
        "assetTypeName":"角色",
        "name":"lyss",
        "isSelect":0,
        "id":65195
    },
    {
        "englishName":"mkkm",
        "assetTypeName":"角色",
        "name":"mkkm",
        "isSelect":0,
        "id":65194
    },
    {
        "englishName":"asset-01",
        "assetTypeName":"角色",
        "name":"asset-01",
        "isSelect":0,
        "id":34964
    }
]
2.拿获取的唯一的name对应的json和最开始的chooseList进行对比：

List<JSONObject> chooseList3= new ArrayList<>();
for(int i=0;i<chooseList.size();i++){
    JSONObject map= new JSONObject();
    String name  =  chooseList.get(i).get("name").toString();
    map.put("id", chooseList.get(i).get("id"));
    map.put("name", chooseList.get(i).get("name"));
    map.put("englishName", chooseList.get(i).get("englishName"));
    map.put("assetTypeName", chooseList.get(i).get("assetTypeName"));
    chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect"));
   System.out.println("=====3333=====:"+chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()));
   System.out.println("======22====:"+chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect")).collect(Collectors.toList()));
   if(chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect")).collect(Collectors.toList()).contains(1)){
       map.put("isSelect",1);
   } else{
       map.put("isSelect",0);
   }
   chooseList3.add(map);

}
