parsing json using Gson which has objects with same field name

I have a json file which has following structure:

{
"Otions": true
"Plastic": ""
"Houses": {
   7: {
   "name": "Akash Bhawan"
   "MemBers": 3
   "children": 1
   }-
   8: {
   "name": "Ashiyana"
   "memBers": 4
   "children": 2
   }-
   9: {
  "name": "Faruks Nest"
  "memBers": 5
  "children": 1
  }-

The objects inside Houses are variable and can increase or decrease accordingly and also change names. How ever the fieds "name", "members", "children" are the only fields and will always be there

i am using gson to parse 

@SerializedName("Otions")
private String Options;
@SerializedName("Plastic")
private String plastics;
@SerializedName("Houses")
private Houses houses;

i want to know if there is a way we can i can store differently named objects in a hashtable or some other way?

You should do something like (as said in my comment):

JSONObject jsonHouses = jsonObject.getJSONObject("Houses");
Iterator<String> keys = jsonHouses.keys(); //this will be array of "7", "8", "9"

if (keys.hasNext()) {
    JSONObject singleHouseObject = jsonHouses.getJSONObject(keys.next());
    //now do whatever you want to do with singleHouseObject.
    //this is the object which has "name", "MemBers", "children"
}

If you can't change the structure then you have to make house as Hashmap of int to object. For Example:-

HashMap<int, Object> House;

And that object will have elements like name, memBers, details.

Please make "house" as bunch of array instead of objects.

{
    "Options": true,
    "Plastics": "",
    "house": [{
        "name": "Akash Bhawan",
        "MemBers": 3,
        "children": 1
    }, {
        "name": "Ashiyana",
        "memBers": 4,
        "children": 2
    }, {
        "name": "Faruks Nest",
        "memBers": 5,
        "children": 1
    }]
}

Houses should be a map like this.

private HashMap houses.

Since the 3: indicates an index-structure. Gson will create the nested objects as needed.
