Parse JSON to POJO using Java

JSON response:

{"restRequest":{"id":1619,"sessionId":"b6f67825-1ed5-43e1-ba5f-1324550f5798",
"loanId":1123456,"creationDate":1392420577000,"knowledgeBaseName":"automation.drl"},
"finalOutcomeStatus":"REVIEW"}

Parsing the JSON to POJO:

private List<RESTResponseModel> restResponseArray = new ArrayList<RESTResponseModel>();
JSONArray jsonResponse = new JSONArray(getJsonResponse());
for (int k = 0; k<jsonResponse.length();k++){
    RESTResponseModel dm = new RESTResponseModel();
 	JSONObject restRequest=jsonResponse.getJSONObject(k);
	JSONObject restBody = restRequest.optJSONObject("restRequest");
	dm.setId(restBody.optString("id"));
	dm.setSessionId(restBody.optString("sessionId"));
	if (new Long(restBody.optLong("creationDate"))!=null){
		Date date = new Date(restBody.optLong("creationDate"));
		dm.setCreationDate(new SimpleDateFormat("MM/dd/yyyy").format(date));
    }
	dm.setKnowledgeBaseName(restBody.optString("knowledgeBaseName"));
	dm.setFinalOutcomeStatus(restRequest.optString("finalOutcomeStatus"));
	restResponseArray.add(dm);
}
