Importing JSON into an Netbeans project

As the article says you need to add the simple-json library to your project:

http://code.google.com/p/json-simple/

For this we have to add Class org.json.JSONObject which available in json-20131018.jar. We need to download this jar and add this jar to your buildpath.

for it in netbeans right click 'libraries' in the project list, then click add jar/folder.
