Parsing JSON server response into JSON Array

Question

I am using Java to parse a JSON response from a server. My end goal is to have the data from results in an Array. Currently I am using this to try and get the results:

JSONArray jArray = myResponse.getJSONArray("results");

This code fails because it is looking for an array of objects, rather than an array of strings:

org.json.JSONException: Value blah at 0 of type java.lang.String cannot be converted to JSONObject

This is my server's JSON Response:

{
  status: "OK",
  results: [
    "blah",
    "bleh",
    "blah"
  ]
}

Is there a simple way to get the "results" value into an array? Or should I just write my own parser.

Thanks

---------- UPDATE ----------

Looks like my problem was actually occuring somewhere else, and not where the JSON attribute "results" was being converted into a JSONArray.

Sorry and thanks for the answers, they helped me realize I was looking in the wrong spot.

This should be it. So you're probably trying to get JSONObject instead of String inside the results aarray.

JSONObject responseObject = new JSONObject(responseString);
JSONArray resultsArray = responseObject.getJSONArray("results");
for (int i=0; i<resultsArray.length(); i++)
    String resultString = resultsArray.getString(i);

As you will probably have more properties, than only the String[] result, I recommend to define a DTO like this:

public class Dto {
    //of course you should have private fields and public setters/getters, but this is only a sample
    public String status;
    public List<String> results;//this can be also an array
}

And then in your code:

ObjectMapper mapper = new ObjectMapper();
Dto dto = mapper.readValue(inputDtoJson, Dto.class);//now in dto you have all the properties you need
