How do I store images in a zip file in Java

[mglover]

Hi,

I am trying to write some code to collect a load of images from URLs and then to store them in a zip file. So I have written code to get each image into an Image object thus:-

// create the zip file/stream
FileOutputStream dest = new FileOutputStream("d://images.zip");
out = new ZipOutputStream(new BufferedOutputStream(dest));

while ( (record=dis.readLine()) != null ) { // This is reading a text file containing the list of images

String URLStr = UrlStem + record;
URL url = new URL(URLStr);
URLConnection urlconnection = url.openConnection();
image = ImageIO.read(url);

// Now want to add this image to a zip file - but how??
...
}

but I can't see how to then how to add it to a zip file. The images might be GIFs or JPEGS. I have seen examples of adding files from a directory but not of doing it on the fly - is it possible?

Thanks in advance

As long as you know what type the file is at the time you are writing it, I don't see why you can't do it on the fly. Just create the ZipEntry with the known extension and write the bytes to that
