There is a missing constructor in the ImageButton() class. It is in the
downloadable example code, but not in the book. So this:

public class ImageButton extends JButton {

public ImageButton(ImageIcon icon) {

should be changed to:

public class ImageButton extends JButton {

public ImageButton(String img) {
this(new ImageIcon(img));
}

public ImageButton(ImageIcon icon) {

g and g2 both refer to the same object, so the code works with or without
this change. g2 is only needed in order to call Graphics2D methods on the object. I think the reader
is asking for a simple refactoring: since the if and else blocks both end with super.paint(g), the if
could end with the transform, the else could be eliminated, and you could then fall through to
super.paint(g). That's not really important, but it is cleaner, so let's change that part of example
7-6 from:

public void paint (Graphics g) {
if (g instanceof Graphics2D) {
Graphics2D g2 = (Graphics2D) g;
AffineTransform flipTrans = new AffineTransform();
double widthD = (double) getWidth();
flipTrans.setToTranslation (widthD, 0);
flipTrans.scale (-1.0, 1);
g2.transform (flipTrans);
super.paint(g);
} else {
super.paint(g);
}
}

to:

public void paint (Graphics g) {
if (g instanceof Graphics2D) {
Graphics2D g2 = (Graphics2D) g;
AffineTransform flipTrans = new AffineTransform();
double widthD = (double) getWidth();
flipTrans.setToTranslation (widthD, 0);
flipTrans.scale (-1.0, 1);
g2.transform (flipTrans);
}
super.paint(g);

I'm pretty sure the audience will know what a Vector is, but if we need to clarify we should
modify the last sentence of the first paragraph like this:

'opening the door for a completely vector drawn (meaning with shapes instead of images) Swing Look
and Feel'

Change to 'due to a change in screen resolution, for example'
