Answer by SHartley for Sorting a JSON object in Android studios (java)

I'm only familiar with using Google's gson library which is a bit old. If there are better json parsers available I'm sure somebody can chime in.You'd use it like this to extract the information:

String restaurantName;JsonElement restaurantJSONElement;JsonPrimitive restaurantJSONPrimitive;JsonParser parser = new JsonParser();// myJSONstring is the raw JSON dataJsonElement parentJSONElement = parser.parse(myJSONstring);JsonObject parentJSONObject = parentJSONElement.getAsJsonObject();JsonArray restaurantsJSONArray = (JsonArray) parentJSONObject.get("restaurants");for(int i=0;i<restaurantsJSONArray.size();i++){  //get the element  restaurantJSONElement = ((JsonObject)restaurantsJSONArray.get(i)).get("restaurant");  //get the restaurant name  restaurantJSONPrimitive = ((JsonObject)restaurantJSONElement.getAsJsonObject()).getAsJsonPrimitive("name");  restaurantName = restaurantJSONPrimitive.getAsString();}

You could extract all the members and do whatever you want with them, put them in custom object arrays and sort them by restaurantName as the comparitor
