Answer 1

The code should be

import net.sf.json.JSONObject;
JSONObject JSO = JSONObject.fromObject(practiceInfoByUsername);

Also you need json-lib jar, can be downloaded here.

Answer 2

I would recommend you to use a library for json .. there are plenty of them. The most used (from what I know), is google-gson .. good documentation and examples along the web also ..

You can also take a look here .. for an overview of the JSON-tools.
