Java- Convert bufferedimage to byte[] without writing to disk

Question

I\'m trying to send multiple images over a socket using java but I need a faster way to convert the images to a byte array so I can send them. I tried the following code but

Answer 1

The code below it's really fast (few milliseconds)

import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public byte[] toByteArray(BufferedImage image) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();            
    JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(baos);
    encoder.encode(image);            
    return baos.toByteArray();
}
