You can do like this

ArrayList<URL> urlList = new ArrayList();
urlList.add(new URL("http://www.autoguide.com/auto-news/wp-content/uploads/2012/12/mazda-2013-tokyo-auto-salon.jpg"));
urlList.add(new URL("http://www.autoguide.com/auto-news/wp-content/uploads/2012/12/mazda-2013-tokyo-auto-salon.jpg"));
urlList.add(new URL("http://www.autoguide.com/auto-news/wp-content/uploads/2012/12/mazda-2013-tokyo-auto-salon.jpg"));
urlList.add(new URL("http://www.autoguide.com/auto-news/wp-content/uploads/2012/12/mazda-2013-tokyo-auto-salon.jpg"));
int i = 1;
for (URL url : urlList) {
  InputStream in = url.openStream();

  OutputStream out = new FileOutputStream("image" + i + ".png");
  i++;
  int r;
  while ((r = in.read()) != -1) {
   out.write(r);
   }
   in.close();
   out.close();
 }

and more simple

ArrayList<String> imageNames = new ArrayList();
imageNames.add("mazda-2013-tokyo-auto-salon.jpg");
imageNames.add("mazda-2013-Volkswagen-CrossBlue-main.jpg");
for ( String imageName : imageNames) {
    URL url = new URL("http://www.autoguide.com/auto-news/wp-content/uploads/2012/12/"+imageName);
    InputStream in = url.openStream();
    OutputStream out = new FileOutputStream(imageName);
    int r;
    while ((r = in.read()) != -1) {
        out.write(r);
    }
    in.close();
    out.close();
}
