Explain how to make a connection to a URL
Connection to the remote object represented by the URL is only initiated when the connect() method of the URLConnection is called. Doing this initializes a communication link between your Java program and the URL over the network.
The following code show how a connection to a URL is made.
URL xyz = new URL(http://www.xyz.com/);
URLConnection xyzConnection = xyz.openConnection();
catch (MalformedURLException e)
// new URL() failed
. . .
catch (IOException e)
// openConnection() failed
