Resizing 320x480 image into 20x80

Question

How do i resize an 320x480 size image to 20x80
I tried getScaledInstance but it cuts the image rather than resizing it.
I tried the following code:-
BufferedImage bi1 = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
Image img2 = bi1.getScaledInstance(20,80,Image.SCALE_AREA_AVERAGING);
BufferedImage bi = new BufferedImage(img2.getWidth(null), img2.getHeight(null), BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = bi.createGraphics();
g2.drawImage(img, null, null);

Yeah i got my mistake.Sorry
The new code below.The code now generates a black image. public static void saveJPG()
   String s= "d:\\test.jpg";
   URL pic = null;
        BufferedImage bi1 = null;
        try {
            pic = new URL("http://pscode.org/media/stromlo1.jpg");
            bi1 = ImageIO.read(pic);
        } catch (Exception e) {
            e.printStackTrace();
        // BufferedImage bi1 = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
        Image img2 = bi1.getScaledInstance(32, 64, Image.SCALE_AREA_AVERAGING);
        BufferedImage bi = new BufferedImage(img2.getWidth(null), img2.getHeight(null), BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = bi.createGraphics();
        g2.drawImage(img2, null, null);
        FileOutputStream out = null;
        try {
            out = new FileOutputStream(s);
        } catch (java.io.FileNotFoundException io) {
            System.out.println("File Not Found");
        JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
        JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
        param.setQuality(0.5f, false);
        encoder.setJPEGEncodeParam(param);
        try {
            encoder.encode(bi);
            out.close();
        } catch (java.io.IOException io) {
            System.out.println("IOException");
}
