Download animated gif images in Java

Question

I'm trying to download an animated gif image using Java, but the downloaded image loses animation. Here is my code:

    BufferedImage image = ImageIO.read(new URL("http://gifntext.com/images/football_small.gif"));
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream);
    image.flush();
    ImageIO.write(image, "gif", bufferedOutputStream);
    bufferedOutputStream.flush();

    byte[] bytes = outputStream.toByteArray();
    File file = new File("/home/toan/football_small.gif");
    FileOutputStream out = new FileOutputStream(file);

    out.write(bytes);
    out.flush();
    out.close();
    outputStream.close();
    bufferedOutputStream.close();

Anything wrong with this piece of code? Thanks in advance.

I'm curious, why use `ImageIO` if you just want to download a file? — mzc, Nov 12 '15 at 12:03

GIF is collection of frames and you have to read those frames. Try this :
