you have to make something like this

JSONObject jsonObject = new JSONObject(response);

JSONArray resultVal = jsonObject.getJSONArray("Data");

JSON data are objects parsed into a string for mostly NoSQL purposes and they can be parsed into objects. Gson is one of the libraries which is easy to use to parse your JSON data.

If you get jsonData as the response string which has Data, the following code can parse the custac in the list of array. But, firstly you have to create an object for Data

Data[] dataCollection = new Gson().fromJson(json,Data[].class);

Data must contain the attributes like CustomerID, FirstName, etc.

For your case,

class Data{
    private String CustomerID;
    private String FirstName;
    private String LastName;
    private String NickName;
    private int FundAmount;
    private ArrayList<Custac> custac;
    class Custac{
        // Write your attributes as shown above.
    }
}

Try This Code

JSONArray custac;
 try {

    JSONArray resultVal = jsonObject.getJSONArray("Data");
    for (int i = 0; i < resultVal.length() - 1; i++) {
        jsonObject = resultVal.getJSONObject(i);
        custac = jsonObject.getJSONArray("custac");

        Log.d("TAG, custac + "");
    }
} catch (JSONException e) {
    e.printStackTrace();
}
