Retrieving nested arrays values with JSON Java

Question

I\'m struggling to retrieve some values from a JSON file formatted like this one:

{
  \"search\": {
    \"entry\": [
      {
        \"found\": \"identity=94         


        

Answer 1

Libraries used:

import org.json.simple.JSONArray;
import org.json.simple.JSONObject;

Check the below code and step wise parsing

    JSONObject search = (JSONObject) jsonObject.get("search");//1
    JSONArray entry = (JSONArray) search.get("entry");//2
    for (int i = 0; i < entry.size(); i++) {
        JSONObject jsonObject1 = (JSONObject) entry.get(i);//3
        JSONArray jsonarray1 = (JSONArray) jsonObject1.get("attribute");//4
        for (int j = 0; j < jsonarray1.size(); j++) {
            System.out.println(((JSONObject) jsonarray1.get(j)).get(
                    "value").toString());//5

        }

    }

It will give the values mentioned step wise:

1) {"entry":[{"found":"identity=9454532,l=big,ton=grand,k=molvi","attribute":[{"name":"firstname","value":["Lucas"]},{"name":"lastname","value":["Brandon"]}]}],"return":{"code":0,"count":1,"message":"Success"}}

2) [{"found":"identity=9454532,l=big,ton=grand,k=molvi","attribute":[{"name":"firstname","value":["Lucas"]},{"name":"lastname","value":["Brandon"]}]}]

3) {"found":"identity=9454532,l=big,ton=grand,k=molvi","attribute":[{"name":"firstname","value":["Lucas"]},{"name":"lastname","value":["Brandon"]}]}

4) [{"name":"firstname","value":["Lucas"]},{"name":"lastname","value":["Brandon"]}]

5) ["Lucas"] and ["Brandon"]

So basically you have to take care of JSONObject and JSONArray respectively and do the parsing accordingly.
