I'm studying up on the Printable interface and am trying to use an example from a book. I'm getting compile errors on the variable g2, (Marked in code).
Since class Graphics2D is abstract and I'm subclassing from parent Graphics g, I don't understand what the compiler wants.
This is just part of the code containing the class.
Thanks...

int y = g2.getFont().getSize() * 5 / 2;
