1. A URLConnection object represents a connection to a remote machine.

3. To obtain an instance of URLConnection, call the openConnection method on a URL object.
4. To use a URLConnection object to write: set the value of doOutput to true using setDoOutput methods:

URL url = new URL ("http://www.google.com/");
InputStream inputStream = url.openStream ();

has the same effect as

URLConnection urlConnection = url.openConnection ();
InputStream inputStream = urlConnection.getInputStream ();
