        String httpsURL = "https://maven.apache.org/guides/mini/guide-repository-ssl.html";

        URL myurl = new URL(httpsURL);
        HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection();

        InputStream ins = con.getInputStream();
        InputStreamReader isr = new InputStreamReader(ins);
        BufferedReader in = new BufferedReader(isr);
        String inputLine;

        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
