Thread: JSON reader

I've done a search on these forums and exhausted my link supplies on google so it's time to ask my question here.


Quite simply I've got an application that connects to a website and gathers the JSON string but now I can't figure out how to parse the information.... it seemed to much easier in php.

I've tried using some of the json libraries available, such as gson and other various ones found at json.org, but simply can't figure it out as they all seem to over complicate what I'm trying to do.


So does anyone have an explanation on how I can do this without using an API that simply over complicates it or perhaps a source that will explain things a little more clearly for me to be able to use this information?



Thanks in advance.

awww no one


Guess I'll get cracking on it again this morning.

After digging through a ton of stuff this morning I finally came across the answer I was looking for. Hopefully this will help someone else out that does a search on the forums with the same problem:

Solution:

You've got to use one of the many APIs out there, for my simple task of just reading the string I chose to use JSON-Simple. After that the codes pretty simple it just took me a really long time to find out how simple it was as the documentation is overly complicated for the task... here's the link I followed: LINK.


I hope this helps make it easier on anyone else that ran into the problem.

OK, ran into another problem.

Keep getting an error when I try to read an array in the object... Here's the chunk of code that's giving me the problem:

			Object obj = parser.parse(json);
			JSONObject jsonObject = (JSONObject) obj;
 
			JSONArray msg = (JSONArray) jsonObject.get("guild");
			Iterator<String> iterator = msg.iterator();
			while (iterator.hasNext()) {
				System.out.println(iterator.next());
			}

And here's the error message:

java.lang.ClassCastException: org.json.simple.JSONObject cannot be cast to org.json.simple.JSONArray

I understand what the error message is saying I just can't seem to figure out a solution to get it to work.

Simple answer: it wasn't an array in the json feed it was another object... all you had to do was make another object.
