Convert InputStream to JSONObject

Question

I am converting InputStream to JSONObject using following code. My question is, is there any simple way to convert InputStream to JSONObject. Without doing InputStream -> BufferedReader -> StringBuilder -> loop -> JSONObject.toString().

    InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
    BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStreamObject, "UTF-8"));
    StringBuilder responseStrBuilder = new StringBuilder();

    String inputStr;
    while ((inputStr = streamReader.readLine()) != null)
        responseStrBuilder.append(inputStr);

    JSONObject jsonObject = new JSONObject(responseStrBuilder.toString());

Since you're already using Google's Json-Simple library, you can parse the json from an InputStream like this:

InputStream inputStream = ... //Read from a file, or a HttpRequest, or whatever.
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject)jsonParser.parse(
      new InputStreamReader(inputStream, "UTF-8"));
