In (Graphics g) method...is g an object of Graphics2D?

[Vasiq Molvizadah]

I'm reading Head First Java ...and in the GUI chapter it says that...in the method

void paintComponent (Graphics g)

"The object referenced by the "g" parameter is actually an instance of the Graphics2D class."

I don't get this statement..because Graphics2D is a subclass of Graphics class...
Any help on this...guys

It means you can treat the Graphics object like a Graphics2D object by casting it:

Graphics2D g2d = (Graphics2D)g;
