Image frames from GIF not working properly

Question

I want to try and save all the frames from a GIF but it either doesn't write the image or if I try another method, it gives an error.

I have

public static void encryptionGIF () throws IOException {
    ImageReader GIFReader = (ImageReader)ImageIO.getImageReadersByFormatName("gif").next();
    File input = new File("Test.gif");
    ImageInputStream Stream = ImageIO.createImageInputStream(input);
    GIFReader.setInput(Stream);
    int frames = GIFReader.getNumImages(true);
    for (int i = 0; i < frames; i++) {
        BufferedImage frame = GIFReader.getRawImageType(i).createBufferedImage(GIFReader.getWidth(i), GIFReader.getHeight(i));
        File output = new File ("Test" + i + ".png");
        ImageIO.write(frame, ".png", output);
    }
}

I have also tried replacing

BufferedImage frame = GIFReader.getRawImageType(i).createBufferedImage(GIFReader.getWidth(i), GIFReader.getHeight(i));

with

BufferedImage frame = GIFReader.read(i);

and get the error:

Exception in thread "main" javax.imageio.IIOException: I/O error reading image!
