Parsing JSON Output using JAVA

Use the JSONParser methods to parse a response that’s returned from a call to an external service that is in JSON format, such as a JSON-encoded response of a Web service callout.

Here is the code to parse the JSON string using JAVA:

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

public class JsonParser {
 
 public static void main(String args[]) throws ParseException{
  
  String Response = "{\"Profile\":{\"Name\":\"Sarthak\", \"Age\":\"23\"," + "\"Address\":\"Lucknow\"} }";

  JSONParser parser = new JSONParser();
  Object obj = parser.parse(Response);

  JSONObject jsonObject = (JSONObject) obj;
  JSONObject jsonObject1 = (JSONObject) jsonObject.get("Profile");
  String name = (String) jsonObject1.get("Name");
  Long age = new Long((String) jsonObject1.get("Age"));
  String address = (String) jsonObject1.get("Address");
  System.out.println(name);
  System.out.println(age);
  System.out.println(address);

 }

}
