How do I make a connection to URL?


You obtain a URL instance and then invoke openConnection on it. URLConnection is an abstract class, which means you can't directly create instances of it using a constructor. We have to invoke openConnection method on a URL instance, to get the right kind of connection for your URL. Eg. URL url;
URLConnection connection; try{ url = new URL("..."); connection = url.openConnection(); }catch (MalFormedURLException e) { }
