    There are external tools that can help you do this. Check out JMimeMagic and JMagick. You can also attempt to read the file using the ImageIO class, but that can be costly and is not entirely foolproof.

    BufferedImage image = ImageIO.read(new FileInputStream(new File(..._)));

    This question has been asked on SO a couple of times. See these additional threads on the same topic:
