Parsing stringify string in JAVA

I do have string

{"version":"T2"}

I was reading it from webview and storing it in variable s. <br/>
I want to parse the value of version. So

   try {
         s= s.replaceAll("\n", "\\n");
        JSONObject json = new JSONObject(s);
        Log.d("SAVE_LOG", (String) json.get("version"));
       } catch (JSONException e) {
         Log.d("SAVE_LOG", String.valueOf(e));
         e.printStackTrace();
       }

I found this code from every site. <br/>
But it is giving me this error.

> org.json.JSONException: Value {"version":"T2"} of type
> java.lang.String cannot be converted to JSONObject

<br/>

public class NewClass {
	
	public static void main(String[] args) {
		 try {
			 String s = "{\"version\":\"T2\"}";
	         s= s.replaceAll("\n", "\\n");
	         JSONObject jsonObject = new JSONObject(s);
	        
	        System.out.println(jsonObject.get("version"));
	       } catch (JSONException e) {
	         e.printStackTrace();
	       }
	}

}

Output :
