How to parse the following JSON array?

I am having hard time to figure it out how to parse the following JSON (Dynamic):

[{
"existingData": [
  0,
  0
],
"guestId": {
  "__type": "Pointer",
  "objectId": "EB1rr6Lqtp"
},
"listingAddressGeopoint": {
  "__type": "GeoPoint",
  "latitude": 36.002702,
  "longitude": -78.90682099999998
},
"numberOfListingImages": 1,
"preferredGender": "\"Female\"",
"urlOfListingBeds": [
  "https://xyz.image0.jpg"
],
"urlOfPrimaryImage": null,
"createdAt": "2015-09-09T14:54:36.139Z",
"updatedAt": "2015-09-15T14:46:41.988Z",
"user": {
  "createdAt": "2015-09-09T14:54:34.841Z",
  "updatedAt": "2015-09-09T14:54:34.841Z"
   }
}]

The problem is sometime data starts previuosData not from existingData. How can I get the array of urlOfListingBeds in list of Some object?

Model class

public class Image {
    public List<String> urlOfListingBeds;
}

Edit-1

I tried to access it by following code but it is throwing an errror

 for (int i = 0; i < rjson.size(); i++) {
        rjson.getAsJsonObject(i);
    }

where as rjson is JsonArray

Get the JsonArray from json object by calling getAsJsonArray(). Create a iterator by calling JsonArray#iterator, and iterate over each JsonElement, and get JsonObject by calling JsonElement#getAsJsonObject().

Once you have JsonObject, you will find the urlOfListingBeds.

Code:

JsonArray array= rjson.getAsJsonArray();
Iterator iterator = array.iterator();
List<String> urlOfListingBeds = new ArrayList<String>();
while(iterator.hasNext()){
    JsonElement jsonElement = (JsonElement)iterator.next();
    JsonObject jsonObject = jsonElement.getAsJsonObject();
    JsonArray urlOfListingBed = jsonObject.getAsJsonArray("urlOfListingBeds");
    if(urlOfListingBed!=null){
        Iterator iter = urlOfListingBed.iterator();
        while(iter.hasNext()){
            JsonElement jsonElementChild = (JsonElement)iter.next();
            if(jsonElementChild!=null)
                urlOfListingBeds.add(jsonElement.getAsString());
        }
    }
}
