HttpURLConnection class is an abstract class directly extending from URLConnection class. It includes all the functionality of its parent class with additional HTTP-specific features. HttpsURLConnection is another class that is used for the more secured HTTPS protocol.
The method is used to enable streaming of a HTTP request body without internal buffering, when the content length is not known in advance. It sets whether HTTP redirects (requests with response code) should be automatically followed by HttpURLConnection class.
HttpsURLConnection extends HttpURLConnection , and your connection is an instance of both. When you call openConnection() the function actually returns an HttpsURLConnection . However, because the https object extends the http one, your connection is still an instance of an HttpURLConnection .
HttpURLConnection connection = null;
try {
URL url = new URL("www.google.com");
connection = (HttpURLConnection) url.openConnection();
connection.connect();
connection.getInputStream();
// do something with the input stream here
} catch (MalformedURLException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
} finally {
if(null != connection) { connection.disconnect(); }
}
