Write JAVANIO

URL website = new URL("http://www.website.com/information.asp");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream("information.html");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);

The transferFrom() method is much more efficient than simply turning around and reading the loop because it can transfer bytes into the file system cache without actually copying it.
