import java.net.URL;
import java.net.URLConnection;
 
public class Main {
   public static void main(String[] args) throws Exception {
      int size;
      URL url = new URL("http://www.runoops.com/wp-content/themes/runoops/assets/img/newlogo.png");
      URLConnection conn = url.openConnection();
      size = conn.getContentLength();
      if (size
