学了这么久的java，感觉java还是有很多模式在编程中可以套用的。
如果要将某个URL对应的网页下载下来，并对其进行操作就可以用下面的模式
public class Down
    {
        public Down(String urlstring )
        {
            URL url;
            InputStream in;
            OutputStream out;
            try {
                url = new URL(urlstring);
                in = url.openStream();
                int c;
                while ((c = in.read()) > -1) {
                     // do something you want to do
                }
                in.close();
            } catch (IOException e) {}
        }
    }
