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();

BufferedImage image = ImageIO.read(imageUrl);

The ImageIO class provides a number of methods for reading images from different sources.

// Get the input stream to read the image from
// NB. getImageStream() is an arbitrary method
// thats returns the input stream to read the
// image from

InputStream in = getImageStream();

// load the image from the stream

BufferedImage image = ImageIO.read(in);
