Answer: A Canvas object provides access to a Graphics object via its paint( ) method.
Answer: The Canvas, Frame, Panel and Applet classes support painting.
Answer: The paint( ) method supports painting via a Graphics object. The repaint( ) method is used to cause paint( ) to be invoked by the AWT painting method.
Answer: The FontMetrics class is used to define implementation-specific properties, such as ascent and descent, of a Font object.
(a). A Canvas object
(b). A Graphics object
(c). An Image object
(d). A paint object
Answer: (b). A Graphics object
