Serious problems with paint method, need major help

Question

I've got a mjor problem with displaying a BufferedImage Object. My program takes in an image, i call a method on it which creates an ImageObject, imgObj, which contains the following values:
Image width, called width
Image height, called height,
array of 8 bit integers for the ARGB value of each pixel, called int [] imgCol
I've managed to create a Buffered Image of the form:
//make a buffered image ready to take the array of pixels
bufferedImage = new BufferedImage( imgObj.width, imgObj.height, BufferedImage.TYPE_INT_ARGB);
Then I set the ARGB values in the BufferedImage, by specifying the integer array of pixels, imgCol:
//set the values in the buffered image using buffered image method
bufferedImage.setRGB( 0, 0, imgObj.width, imgObj.height, imgObj.imgCol, 0, imgObj.width);
Then I try to paint it, callling repaint() in the same method as the code above.
Now when I try the following stuff I get a Null Pointer Exception:
public void paint(Graphics g){
     paintImage(g);
public void paintImage(Graphics g){
     Graphics2D ImageGraphic2 = (Graphics2D)g;
     // Draws the buffered image to the screen.
     ImageGraphic2.drawImage(bufferedImage, 0, 0, this);
Can anyone help me in fixing this problem?
