Java下载指定URL的HTML源码，Java实现 输入一URL显示返回的HTML内容？

URL url = new URL("http://www.sina.com.cn");
        InputStream is = url.openStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(is));
        String line = "";
        while (line != null) {
            line = br.readLine();
            System.out.println(line);
        }
