        } catch (IOException e) {
            e.printStackTrace();
        }

There is quite a bit of the HTML missing from that text: the DOCTYPE header and the HTML head and body tags.

You need to study the documentation for the URLConnection (Java Platform SE 7 )[^] class. It explains there how to access the complete details of the HTML.
