Json String can't decode using json-simple toolkit java

Question

String login = "{\"result\":[104192,42068],\"id\":1}";

Object obj = JSONValue.parse(login);

JSONArray array = (JSONArray)obj;

This throw a exception

Exception in thread "main" java.lang.ClassCastException: org.json.simple.JSONObject cannot be cast to org.json.simple.JSONArray

What is the problem in this code ?

In this case the parsed result is a JSONObject so you need to cast it to that.

What if the JSONObject is used as an object elsewhere? Why is the cast on assignment not enough?

You are trying to cast an object into an array. Try adding the object to the array instead.

I had this problem and I have fixed it. Here is my code snippet:

Object obj = JSONValue.parse(response.getBody());
JSONObject jsonObject = (JSONObject) obj;
Object gu_obj = jsonObject.get("guid");

I got the yahoo user guid from the request body. Hope this helps :)
