How to parse list of object from Json Object

Question

I need help to parse this JSON, i have some problems.

The object name is "random"
I need to create Java object with list of generic objects and parse Json
How i can parse every object with random object name.

The Json to Parse example 1 :

{
   "object_name_1":{
      "id":0,
      "value_1":"hello",
      "value_2":"test",

   },
   "object_name_2":{
      "id":1,
      "value_1":"hello",
      "value_2":"test",

   },"object_name_3":{
      "id":2,
      "value_1":"hello",
      "value_2":"test",

   }
}

The Json to Parse example 2 :

{
   "test_object":{
      "id":0,
      "value_1":"hello",
      "value_2":"test",

   },
   "object_name_2":{
      "id":1,
      "value_1":"hello",
      "value_2":"test",

   },
"new_object":{
      "id":2,
      "value_1":"hello",
      "value_2":"test",

   }
}

NB: This is a JSON Object not Json Array and i have output from API so i can't change Json Output

Thank you.

answer as always is: iterate the keys (asked so many times that you would find similar question) — Selvin, Oct 17 '17 at 10:49

You can use [GSON](http://www.javacreed.com/simple-gson-example/) - here is a small example — Daniel Stiefel, Oct 17 '17 at 11:24

This format of json is not Appropriate.you can change format and use array for sequential keys. but you can use below approach:

JSONObject object = new JSONObject(message);
Iterator<String> keyList = object.keys();

while (keyList.hasNext()){
     String key = keyList.next();
     object.get(key);
     //parse value and use it

}
