IMAGE SCALING in JAVA..(please don give the thumnail.java code)

BufferedImage image = null;
image = ImageIO.read(new File("D:\testimage.jpg"));

int[] rgbdata = new int[width*height];

bytes = new byte[rgbdata.length];
pixelValues = new double[rgbdata.length];

for ( int i = 0; i < bytes.length; i++) {
bytes[i] = (byte) (rgbdata[i] & 0xFF);
pixelValues[i] = (double)(rgbdata[i]);

this is the code to read a test image s pixels into some array[]
now what wod be the code to scale the image to some desired resolution
say newwidth and newheight?

so that the testimage which was havin resolution 640*480 is now having newwidth*newheight as
its resolution wit newwidth*newheight already set beforehand.

its like i want the image to be scaled even before the pixels are manipulated for some purpose

You can scale a BufferedImage using java.awt.image.AffineTransformOp. The AffineTransform would be a scale instance, of course.
