                // Loop through biller Array and find billerID
                for (int i = 0; i < biller.length(); i++)
                {
                    JSONObject billerObj = (JSONObject) biller.get(i);
                    String category = billerObj.getString("billerCategory");


                    //Log.d(TAG, category);

                    if (category.equalsIgnoreCase("Electricity")){

                        JSONObject paraminput = billerObj.getJSONObject("billerInputParams");
                        JSONObject paramInfo = paraminput.getJSONObject("paramInfo");
                        String paramName = paramInfo.getString("paramName");


                        Log.d(TAG, paramName);

                    }
                }
            }

An exception has occured. Search for 'TORR00000SUR04'. It happened that "paramInfo" is an JSONArray at that point.
