I think you should use something like this

try {
            JSONObject root = new JSONObject("yourJsonString");
            JSONArray products = root.getJSONArray("product");

            for (int i = 0; i < products.length(); ++i){
                JSONObject prod = products.getJSONObject(i);

               // now parse product
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

First you need to create a JSONObject passing the JSON string as a parameter:

JSONObject jsonObject = new JSONObject(jsonString);

And then, depending on your needs, you may want to fetch an array, another JSON object or a value of the JSONObject:

JSONArray productArray = jsonObject.getJSONArray("product");
Integer success = jsonObject.getInt("success");

You can iterate over a JSONArray and get all the elements of the array, and do what you want with each object of the array (extract values, fetch arrays or objects of the element, etc):

for (int i = 0; i < productArray.length(); i++) {
    JSONObject product = productArray.getJSONObject(i);
    String description = product.getString("description");
    ...
}
