Assume that we have a POJO class called Post

public List getData(String URL) throws InterruptedException, ExecutionException {
    //This has to be AsyncTask because data streaming from remote web server should be running in background thread instead of main thread. Or otherwise your application will hung while connecting and getting data.
    AsyncTask> getTask = new AsyncTask>(){
        @Override
        protected List doInBackground(String... params) {
            List postList  = new ArrayList();
            String response = "";
            try{
                //Read stream data from url START
                java.net.URL url = new java.net.URL(params[0]);
                HttpURLConnection urlConnection = (HttpURLConnection)
                        url.openConnection();
                BufferedReader reader = new  BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
                String line = "";
                while((line = reader.readLine()) != null){
                    response += line + "\n";
                }
                //Read stream data from url END

                //Parsing json data from reponse data START
                JSONArray jsonArray = new JSONArray(response);
                for(int i=0;i
