Improved Buffering (cont’d) . . .

Then, in paint(), perform a simple check on the offscreen image prior to painting:

public void paint(Graphics g) {

if(offscreen == null) {

offscreen = createImage

(getSize().width,

getSize().height);

}

Graphics osG = offscreen.getGraphics();

/* paint to buffered graphics

object as usual */

This second approach is more efficient, but not as clear to read (at first).
