Although @Kumaraswamy 's approach is good but it will only work for GET requests.
But if you are looking for other options then you should do this instead:

      URL obj = new URL("https://www.google.com");
      HttpURLConnection httpConnection = (HttpURLConnection)obj.openConnection();
      httpConnection.setDoOutput(true); //if you want output
      httpConnection.setRequestMethod("POST"); //request method
      BufferedReader bufferedReader = null;
      if (httpConnection.getResponseCode() == 200) {
        bufferedReader = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));
      } else {
        bufferedReader = new BufferedReader(new InputStreamReader(httpConnection.getErrorStream()));
      } 
      StringBuilder content = new StringBuilder();
      String line;
      while ((line = bufferedReader.readLine()) != null){
        content.append(line).append("\n"); 
      }
      bufferedReader.close();
      final String con = String.valueOf(content); //post wherever you need
