Not able to repaint in java

I am not able to dynamically repaint() inside the Jframe.

public static BufferedImage createBufferedImage(BufferedImage image) 
{
    ColorModel cm = image.getColorModel();
    boolean premultiplied = cm.isAlphaPremultiplied();
    WritableRaster raster = image.copyData(image.getRaster());
    return new BufferedImage(cm, raster, premultiplied, null);
}


public static void main(String[] args) {


BufferedImage img = new BufferedImage(old_width_i, old_height_i, BufferedImage.TYPE_INT_RGB);

img=createBufferedImage(img_white_screen);



JFrame frame=new JFrame();
JLabel label = new JLabel(new ImageIcon(img));
frame.getContentPane().add(label, BorderLayout.WEST);
frame.pack();
frame.setVisible(true); 
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

img.flush();
img=createBufferedImage(img_black_screen);
//  frame.removeAll();
//  frame.revalidate();
//  label.removeAll();
//  label = new JLabel(new ImageIcon(img));
//  frame.getContentPane().add(label, BorderLayout.WEST);

frame.repaint();
}

It basically, creates a screen with the first assignment to the "img" (i.e. img_white_screen) variable and does not change to the second assignment i.e. img_black_screen
