May i know why doesn't the image appear one by one similar to a photo mosaic rendering by using the method below?

     public void paint(Graphics g)
     {
           
                 try
                 {
                       Graphics2D g2 = (Graphics2D) g;
                       float alphaVal;
                       AlphaComposite ac;
                 
                       RenderingHints rh = g2.getRenderingHints();
                       rh.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
                 
                       g2.setRenderingHints(rh);
           
                       String filename = "c:/images/church.jpg";
                 
                       Image img = getToolkit().getImage(filename);
                       
                       // the position of the image
                       AffineTransform aTran = new AffineTransform();
                       aTran.translate(1f, 1f);
                       g2.transform(aTran);
                       
                       //alpha blending when two or more images are blended together
                       alphaVal = alpha;
                       ac = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, alphaVal);
                       g2.setComposite(ac);
                       g2.drawImage(img, new AffineTransform(), this);
                 
                 }
                 catch(Exception e)
                 {}
     
                 Graphics2D g2 = (Graphics2D)g;
                 int w = getWidth();
                 int h = getHeight();
                 int imageWidth, imageHeight;
                 int totalHeight = 84;
                 int totalWidth = 600;

                 float alphaVal;
                 AlphaComposite ac;
                 //int j=0;
                       
                 for(int j=0; j<images.length; j++)
                 {
                       imageWidth = images[j].getWidth();
                       imageHeight = images[j].getHeight();
                 
                       if ((j % 5) == 0)
                       {
                   
                                //x and y axis
                            /*To be able to display all the small images accordingly, need translate (x,y).
                           *Use for loop.*/
                                AffineTransform aTran = new AffineTransform();
                                aTran.translate(0.5f, 0.5f);
                                g2.transform(aTran);
                 
                                // reset x for next row (indeed, even for first row) to be at the
                                // first column of this row
                                x = 0;
                                // increment y to go to the next row
                                y += 84;
                       }
                       
                       x += 122; // same as x = x + 122
                 
                       if(j == 0)
                             alphaVal = alpha;
                       else
                             alphaVal = 1.0f - alpha;
                             ac = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, alphaVal);
                             g2.setComposite(ac);
                             g2.drawImage(images[j], x, y, this);
