A required parameter means that the method/function requires that
a valid value, in this case a graphics object, be passed to it because
no default graphics object is available. In the case of method paint(g)
it wouldn't make sense to draw/paint some default object to the
display window.

g is the argument being passed to paint(g) and since there isn't a
default defined then an argument IS required to be sent when
calling the method.

A required parameter means that the method/function requires that
a valid value, in this case a graphics object, be passed to it because
no default graphics object is available. In the case of method paint(g)
it wouldn't make sense to draw/paint some default object to the

g is the argument being passed to paint(g) and since there isn't a
default defined then an argument IS required to be sent when
