Your JSON data is an object (it starts with a curly brace). In the next inner layer, there is a single array (at key "sports"):

String jsonString = readURL("//my URL is here");
JSONObject result = JSONObject(jsonString);
JSONArray sports = result.getJSONArray("sports");
JSONObject sport = sport.getJSONObject(0);
System.out.println(sport.getString("name"));

I might have used another JSON library than you.

Here is an example of how to read data using Jackson JSON library:

    // create Jackson mapper
    ObjectMapper mapper = new ObjectMapper(); 
    String inputString = "{json goes here...}";
    // parse JSON into JsonNode, now you can navigate the data structure
    JsonNode json = mapper.readTree(inputString);
    // get node
    JsonNode searchResultsNode = json.get("searchResults");
    // get another node from that node
    JsonNode classifiedAdvertsNode = searchResultsNode.get("classifiedAdverts");
    // get it's value as string
    String someValue = classifiedAdvertsNode.asText();

If you need to read a file, just pass the file into mapper.readTree(inputString), it will work just as well.

Pasting my code here, this should help. It shows the package which can be used.

import org.json.JSONException;
import org.json.JSONObject;

public class extractingJSON {

    public static void main(String[] args) throws JSONException {
        // TODO Auto-generated method stub

        String jsonStr = "{\"name\":\"SK\",\"arr\":{\"a\":\"1\",\"b\":\"2\"}}";
        JSONObject jsonObj = new JSONObject(jsonStr);
        String name = jsonObj.getString("name");
        System.out.println(name);

        String first = jsonObj.getJSONObject("arr").getString("a");
        System.out.println(first);

    }

}

I use JSONObject under android but from Oracle docs I see its also available under javax.json package:

http://docs.oracle.com/javaee/7/api/javax/json/package-summary.html

If you want Gson then your code should look like below (sorry not compiled/tested):

/*
{"MsgType":"AB","TID":"1","ItemID":"34532136","TransactTime":1389260033223}
*/

Gson gson = new Gson();

static class Data{
    String MsgType;
    String TID;
    String ItemID;
    int TransactTime;
}

Data data = gson.fromJson(yourJsonString,  Data.class);

Edit your code like this ...this may help you..

JSONObject resultObject = new JSONObject(response);

JSONArray JArray = resultObject.getJSONArray("data");

                for (int t=0; t<JArray.length(); t++) {

                    JSONObject JObject = JtArray.getJSONObject(t);



builder.append(JObject.getString("uid")+": ");
