here is a more traditional way to skin that cat:

// Sockets are a low level tool. For HTTP you will see all the headers

URL url = new URL( "http://www.billabong.com:80/songs/lyrics.txt"; );
URLConnection urlc = (URLConnection)url.openConnection();
urlc.setRequestMethod("GET");

String userAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US;

urlc.setRequestProperty( "Connection", "close" );
urlc.setAllowUserInteraction( false );

urlc.connect();
long length = urlc.getContentLength(); // -1 if not available
// if you want to analyse the URL
String protocol = url.getProtocol(); // http
String host = url.getHost(); // www.billabong.com
String file = url.getFile(); // lyrics.txt
int port = url.getPort();// 80
InputStream is = urlc.getInputStream();
InputStreamReader eisr = new InputStreamReader( is,"UTF-8" );
// usually UTF-8 for Unicode 8-bit giving the full Unicode set, no

BufferedReader br = new BufferedReader( eisr, 4096 /* buffsize */ );

// R E A D
char[] ca = new char[1024];
// -1 means eof.
// You don't necessarily get all you ask for in one read.
// You get what's immediately available.
int charsRead = br.read( ca );
String line;
// File being read need not have have a terminal \n.
// File being read may safely use any mixture of \r\n, \r or \n line
terminators.
line = br.readLine();
// line == null means EOF

Sorry Roedy but should this example code be using HttpURLConnection and not URLConnection to use the setRequestMethod(String) method alone with the associated exceptions Try\Catch block?
