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
