java.awt.geom cloneable shape

This abstract class is a java.awt.Shape that repr esents an ellipse (or a circle). Ellipse2D is a

subclass of RectangularShape, and for this reason, the ellipse is defined by its bounding

rectangle. The width and height of the bounding rectangle specify the length of the two

axes of the ellipse. (If the width and height are equal, the ellipse is a circle.) The X and

Y coordinates of the ellipse specify the upper-left corner of the bounding rectangle;

note that this point actually falls outside of the ellipse. The setFrameFromCenter() method,

inherited from RectangularShape, allows you to define the ellipse by specifying the center

and one corner. Note that Ellipse2D can only repr esent ellipses whose axes are parallel

to the X and Y axes of the coordinate system. In order to work with rotated ellipses,

use the ...
