java - 如何从结构上修改 JsonObject 并替换其某些值？

Question

我在 JsonObject 中有一个 json，例如:

"customer": {    
     "full_name": "John John",  
      "personal": {  
        "is_active": "1",    
        "identifier_info": {  
            "hobbies": [  
                "skiing",
                "traveling"
             ],  
             "user_id": "1234",  
             "office_id": "2345"
         }  
     }  
} 

有没有办法修改JsonObject，以便从identifier_info中完全删除hobbies并保留其余部分不变，然后添加hobbies的内容和其他的一样吗？即

"customer": {    
     "full_name": "John John",  
      "personal": {  
        "is_active": "1",    
        "identifier_info": {  
            "skiing":"expert",
            "traveling":"rarely",
             "user_id": "1234",  
             "office_id": "2345"                                                                                  
         }
     }
}

找到删除 JSON 数组“爱好”并将其直接插入到父 JSON 对象中的完整实现。

  public class ProcessJSONString {

  String data ="{\"customer\": {    \n" +
        "     \"full_name\": \"John John\",  \n" +
        "      \"personal\": {  \n" +
        "        \"is_active\": \"1\",    \n" +
        "        \"identifier_info\": {  \n" +
        "            \"hobbies\": [  \n" +
        "                \"skiing\",\n" +
        "                \"traveling\"\n" +
        "             ],  \n" +
        "             \"user_id\": \"1234\",  \n" +
        "             \"office_id\": \"2345\"\n" +
        "         }  \n" +
        "     }  \n" +
        "}} ";

public void processData() {
    try {
        JSONObject result = new JSONObject(data);
        JSONObject customer = result.getJSONObject("customer");
        JSONObject personal = customer.getJSONObject("personal");
        JSONObject identifierInfo = 
        personal.getJSONObject("identifier_info");
        JSONArray hobbies = identifierInfo.getJSONArray("hobbies");

        identifierInfo.remove("hobbies");

         //Under the assumption the tags will be added by the user, the code has been inserted.
        identifierInfo.put("skiing","expert");
        identifierInfo.put("traveling","rarely");



    } catch (JSONException e) {
        e.printStackTrace();
    }

}

public static void main(String[] args) {
    ProcessJSONString instance = new ProcessJSONString();
    instance.processData();
}
}
