Get Date Taken of an image

I want to find the "Date Taken" of an image and not "date modified" or "date created". Though I have found some links on stackoverflow, but none could retrieve it. The image format is: tiff and RAW.

Using javax.imageio, I wrote the below program, but it prints nothing. Which means there is no reader available

        File file = new File( fileName );
        ImageInputStream iis = ImageIO.createImageInputStream(file);
        Iterator<ImageReader> readers = ImageIO.getImageReaders(iis);            
        if (readers.hasNext()) {
            // pick the first available ImageReader
            ImageReader reader = readers.next();
            // attach source to the reader
            reader.setInput(iis, true);
            // read metadata of first image
            IIOMetadata metadata = reader.getImageMetadata(0);
            String[] names = metadata.getMetadataFormatNames();
            int length = names.length;
            for (int i = 0; i < length; i++) {
                System.out.println( "Format name: " + names[ i ] );
                displayMetadata(metadata.getAsTree(names[i]));
            }
        }

Using the core java libraries, is there a method to access "date taken" and not "date created" or "date modified". Further the data taken info is available as I can see that from image properties in OS

EDIT: It turns out that readers iterator has nothing with it. i.e.e size 0. It is only happening for tiff and raw images. Works well with jpeg

I could not find any solution using java core libraries. Found a library called metadata-extractor which does the job.

More info can be found here.
