The ImageIO class can be used to write an image as a JPEG encoded stream.If you write that stream to a ByteArrayOutputStream then you will end up with a byte array that contains the JPEG encoded image.

ByteArrayOutputStream out = new ByteArrayOutputStream();
ImageIO.write(image, "JPEG", out);
byte[] imageBytes = out.toByteArray();
