how do I scale a BufferedImage

Question

I have viewed this question, but it does not seem to actually answer the question that I have. I have a, image file, that may be any resolution. I need to load that image into a BufferedImage Object at a specific resolution (say, for this example, 800x800). I know the Image class can use getScaledInstance() to scale the image to a new size, but I then cannot figure out how to get it back to a BufferedImage. Is there a simple way to scale a Buffered Image to a specific size?

NOTE I I do not want to scale the image by a specific factor, I want to take an image and make is a specific size.

Something like this? :

 /**
 * Resizes an image using a Graphics2D object backed by a BufferedImage.
 * @param srcImg - source image to scale
 * @param w - desired width
 * @param h - desired height
 * @return - the new resized image
 */
private BufferedImage getScaledImage(Image srcImg, int w, int h){
    BufferedImage resizedImg = new BufferedImage(w, h, BufferedImage.TRANSLUCENT);
    Graphics2D g2 = resizedImg.createGraphics();
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(srcImg, 0, 0, w, h, null);
    g2.dispose();
    return resizedImg;
}
