Am I only checking URL links with this java code?

I have a method that uses a url and finds all the links on this page. However, I am worried that these are only links, when I check to see if links work or not, some of the links seem weird. For example, if I check links to www.google.com, I get 6 broken links that don’t return an http status code, but instead say that there is no protocol for this broken link. I simply would not think that google would have any broken links on the main page. An example of one of the broken links is: / preferences? Hl = en I don’t see where this link is on the google main page. I am wondering if I am checking only links or is it possible I am retrieving code that should not be a link?

Here is a method that checks the URL for links:

public static List getLinks(String uriStr) {

    List result = new ArrayList<String>();
    //create a reader on the html content
    try{
        System.out.println("in the getlinks try");
    URL url = new URI(uriStr).toURL();
    URLConnection conn = url.openConnection();
    Reader rd = new InputStreamReader(conn.getInputStream());

    // Parse the HTML
    EditorKit kit = new HTMLEditorKit();
    HTMLDocument doc = (HTMLDocument)kit.createDefaultDocument();
    kit.read(rd, doc, 0);

    // Find all the A elements in the HTML document
    HTMLDocument.Iterator it = doc.getIterator(HTML.Tag.A);
    while (it.isValid()) {
        SimpleAttributeSet s = (SimpleAttributeSet)it.getAttributes();

        String link = (String)s.getAttribute(HTML.Attribute.HREF);
        if (link != null) {
                // Add the link to the result list
                System.out.println(link);
            //System.out.println("link print finished");
            result.add(link);
        }
        //System.out.println(link);
        it.next();
    }
    }
