Take a look at JSON in Java. It can help you convert JSON strings to java objects and vice versa.

I've used GSON http://code.google.com/p/google-gson/ and I believe it's the best,

First you create a class to hold your JSON structure

Class Room {
    int id;
    int temp;
}

And then you parse your string into a json like this

Gson gson = new Gson();
Room room = gson.fromJson(jsonString, Room.class);
