How can i modify this string and get the value I want from JSON Object in java?

This is the response.

{
  "code": 200,
  "data": {
    "createdAt": "2019-12-09 15:21:07.0",
    "id": 3,
    "title": "{\"v\":\"1\"}",
    "token": "INACTIVE"
  },
  "message": "SUCCESS"
}

I need value of v which is 1. I'm getting this

{"v":"1"}

through 

JSONObject r2 = new JSONObject(operation);
                String title = r2.getString("title");
                System.out.println(title);

How do I get the value of v after this? It would be great if I could get any suggestions.

String v= r2.getJSONObject("title").getString("v");
System.out.println(v);

PS: Don't forget to handle nulls,etc.

UPDATE: Please refer Andreas's answer as it is the correct answer. This answer wrongly assumes that title also contains json.

The value of title is a string with JSON text, so you need to re-invoke the JSON parser.

Also, in the question code, you forgot to navigate past the data node.

JSONObject rootObj = new JSONObject(operation); // parse JSON text
String title = rootObj.getJSONObject("data").getString("title"); // get "title" value
JSONObject titleObj = new JSONObject(title); // parse JSON text
String v = titleObj.getString("v"); // get "v" value
System.out.println(v); // prints: 1
