Answer 1

The method toJSONString() is from json-simple but I guess you are using org.json.

org.json have an alternative to toJSONString(). You can simply use: obj.toString(1).

The difference to the toString() method is, that if you pass "1" as parameter org.json automatically will format and beautify your JSON. So you don't have only one single compressed line of JSON in your file.
