Checking for a webpage

Question

Hi All
How do I check if a particular web page(s) are available ( not return page not found error).
I have a list urls available in a text file like:
http://www.google.com
http://maps.google.com
http://www.cnn.com
Program should go through each of the urls and say if it is available or not.
Please let me know.
Thanks
bib

            "http://www.cnn.com",
            "http://www.cnn.com/nancy_grace"
        for(String url : urls) {
            System.out.format("%s -- response code=%d%n", url, getResponseCode(url));
    public static int getResponseCode(String urlString) throws IOException {
        URL url = new URL(urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
