You don't need to convert the JSON into a Java Object for that you will need to define POJOS. Maybe this will help :-
final ObjectNode yourNode = new ObjectMapper().readValue(<Your_JSON_Input_String>, ObjectNode.class);
if (node.has("URL")) {
System.out.println("URL :- " + node.get("URL"));
}
import org.json.JSONArray;
import org.json.JSONObject;
public class Main {
public static void main(String[] args) throws IOException {
String jsonString = "{\"data\":[{\"url\":\"http://example.com\"}]}";
JSONObject jsonObject = new JSONObject(jsonString); // 1
JSONArray data = jsonObject.getJSONArray("data"); // 2
JSONObject objectAtIndex0 = data.getJSONObject(0); // 3
String urlAtObject0 = objectAtIndex0.getString("url"); // 4
System.out.println(urlAtObject0);
}
}
Get JSON object for whole JSON string
Get data
as JSON array
Get JSON object at desired index or loop on JSON array of previous step
Get url
field of the JSON object
