Modify JSON object in salesforce

Hi,
 
   I am creating JSON object in salesforce using 
  
JSONGenerator gen = JSON.createGenerator(true);

I keep adding some fields and values at different hierarchy in this object, but while doing this if I get some different values later for my other computations, I would like to modify already created values in this above object.

So my question is whether I can modify the JSON object or not ? 
If yes, How? It would be good if you provide some good links or sample code.

Thanks,
Abhishek

 //add the objects
 answers.add(thisAns1);
 answers.add(thisAns2);
 //seraialize them
 String JSONString = JSON.serialize(answers);
 system.debug(JSONString);
 //This dies
 list<surveyAnswer> answersObjs = (List<surveyAnswer>)JSON.deserialize(JSONString,List<surveyAnswer>.class);
