Java URL text file to String

I've hosted a text file which I would like to load into a string using java.

My code doesn't seem to work producing errors, any help?

try {
    dictionaryUrl = new URL("http://pluginstudios.co.uk/resources/studios/games/hangman/dictionary.dic");
} catch (MalformedURLException catchMalformedURLException) {
    System.err.println("Error 3: Malformed URL exception.\n"
                     + "         Dictionary failed to load.");
}
// 'Dictionary' scanner setting to file
// 'src/Main/Dictionary.dic'
DictionaryS = new Scanner(new File(dictionaryUrl));
System.out.println("Default dictionary loaded.");

UPDATE 1: The file doesn't seem to load going to the catch. But the file exists.

JavaDoc tells us:

File(URI uri)

Creates a new File instance by converting the given file: URI into an abstract pathname.

We can't create and use a File instance for any other resource type (like http).

Something like this should work in your case:

DictionaryS = new Scanner(dictionaryUrl.openStream());

You could do something that this tutorial does

   public class WebPageScanner {
     public static void main(String[] args) {
       try {
         URLConnection connection =
           new URL("http://java.net").openConnection();
         String text = new Scanner(
           connection.getInputStream()).
           useDelimiter("\\Z").next();
       } catch (IOException e) {
         e.printStackTrace();
       }
     }
   }

You need to use HttpClient and retrieve the data as a string or string buffer. then use parse or read as file.
