How do I obtain only View count from the following JSON Array?

Question

Here is the JSON response of a video for youtube data analytics:

{

 "etag": "\"q5k97EMVGxODeKcDgp8gnMu79wM/nKD2hgTXHwAf_Y8YHghPkBlZJcs\"",

    },
    "defaultAudioLanguage": "en"
   },

    "dislikeCount": "586",
    "favoriteCount": "0",
    "commentCount": "1397"
   }
  }
 ]

I would only like to extract the viewCount for example from the above response. How do I do that in Java? I have obtained the above response in a string but how do I extract just those single values like viewCount? An example is well appreciated.

You would have to traverse the JSON array to get the viewCount field. I can't give you the exact code to use as you have not told us what JSON library you are using, but here's some pseudocode.

// If json is the object containing the JSON data
viewCount = json["items"][0]["statistics"]["viewCount"];

From the "items" array, you get the first element, then the "statistics" object from that element, then the "viewCount" field from the statistics object.

Try this -

String jsonString="";
JsonParser jParser= Json.createParser(new ByteArrayInputStream(jsonString.getBytes()));
while(jParser.hasNext()){
    if(jParser.next()==Event.KEY_NAME){
        if(jParser.getString().equals("viewCount")){
            jParser.next();
            System.out.println(jParser.getString());
        }
    }
}

The library should be imported correctly. Please refer - https://jsonp.java.net/download.html.
