java.awt.geom.Ellipse2D
The Ellipse2D class describes an ellipse that is defined by a framing rectangle.
This class is only the abstract superclass for all objects which store a 2D ellipse. The actual storage representation of the coordinates is left to the subclass. @version 1.20, 02/24/06 @author Jim Graham @since 1.2
