How to access nested objects of a Json File

Question

the string I have into "jsonString" is the content of this link: http://85.18.173.82/cineca/wp5/json/events.json

Now I want the value "Day" of the second "Event".

JSONObject o = new JSONObject(jsonString);
String day = o.getString("XXXXXXXXXX");
System.out.println(day);

What does I have to put as argument of o.getString?

Many thanks

you really should post the json in your question instead of just posting an external link to it. — Sam I am says Reinstate Monica

JSONObject obj = new JSONObject(json);

JSONArray array = obj.getJSONArray("Events");
for(int i = 0 ; i < array.length() ; i++){
    System.out.println(array.getJSONObject(i).getJSONObject("Event").getString("Day"));
}

In this way, you can access, thanks.

The way you're constructing your JSONObject is wrong. By using this constructor you're not reading the json from that URL, you're actually using that string as a json representation (which it is not).

If you want to first read the json from your URL you'll have to do an HTTP GET request and then construct a JSONObject out of the response.

For more info, take a look at JSONObject docs

Thanks for your answer, I have already done the HTTP request, now I have the content of the file in a string called jsonString.
