BlogReader: I have a JSON file with multiple arrays in it. How do I access the information?

So in the tutorials we were taught how to handle single arrays in the JSON file. In the teamtreehouse blog json the array looked like this:

{

  "status": "ok",

  "count": 20,

  "count_total": 1764,

  "pages": 89,

  "posts": [

        {

              "id": 23705,

              "url": "http://blog.teamtreehouse.com/new-course-wordpress-user-roles",

              "title": "Getting to Grips with WordPress User Roles",

              "date": "2014-06-19 17:51:18",

              "author": "Zac Gordon",

              "thumbnail": "http://blog.teamtreehouse.com/wp-content/uploads/2014/06/pic-of-zac-150x150.png"
         },

In the JSON I am trying to use it looks like this:

{

 "kind": "Listing",

 "data": {

      "modhash": "0h1lsv6zgi590b5c3d88f5798f09f2f1652fd34b06acc2a567",

      "children": [

           {

                "kind": "t3",

                "data": {

                     "domain": "google.com"

           }

My question is: How do I get access to "domain"? Thanks.

Hey! I didn't test it but it should be something like this, try to understand what i've done.

... 
mBlogData
...

JSONObject jsonData= mBlogData.getJSONObject("data");
JSONArray childrenArray = jsonData.getJSONArray("children");

for(int i = 0; i < childrenArray.lenght(); i++) {
      JSONObject childrenData = childrenArray.getJSONObject(i);
      JSONObject data = childrenData.getJSONObject("data");
      String domain = data.getString("domain");
}
