Ellipse2D from the
specified coordinates.

public double getX()
double precision.

double precision.
getY in class RectangularShapepublic double getWidth()
double precision.
getWidth in class RectangularShapepublic double getHeight()
double precision.
getHeight in class RectangularShapepublic boolean isEmpty()
RectangularShape is empty.
When the RectangularShape is empty, it encloses no
area.
isEmpty in class RectangularShapetrue if the RectangularShape is empty;
false otherwise.
public void setFrame(double x,
double y,
double w,
double h)
Shape to the specified rectangular values.

specified rectangular shapey - the Y coordinate of the upper-left corner of the
specified rectangular shapew - the width of the specified rectangular shapeh - the height of the specified rectangular shapeRectangularShape.getFrame()public Rectangle2D getBounds2D()
Shape than the getBounds method.
Note that there is no guarantee that the returned
Rectangle2D is the smallest bounding box that encloses
the Shape, only that the Shape lies
entirely within the indicated Rectangle2D. The
bounding box returned by this method is usually tighter than that
returned by the getBounds method and never fails due
to overflow problems since the return value can be an instance of
the Rectangle2D that uses double precision values to
store the dimensions.
