public abstract class RoundRectangle2D extends RectangularShape
RoundRectangle2D class defines a rectangle with
rounded corners defined by a location (x,y), a
dimension (w x h), and the width and height of an arc
with which to round the corners.
This class is the abstract superclass for all objects that store a 2D rounded rectangle. The actual storage representation of the coordinates is left to the subclass.

Shape intersects the
interior of a specified rectangular area.
The rectangular area is considered to intersect the Shape
if any point is contained in both the interior of the
Shape and the specified rectangular area.
The Shape.intersects() method allows a Shape
implementation to conservatively return true when:
Shape intersect, but
Shapes this method might
return true even though the rectangular area does not
intersect the Shape.
The Area class performs
more accurate computations of geometric intersection than most
Shape objects and therefore can be used if a more precise
answer is required.x - the X coordinate of the upper-left corner

double y,
double w,
double h)
Shape entirely contains
the specified rectangular area. All coordinates that lie inside
the rectangular area must lie within the Shape for the
entire rectangular area to be considered contained within the
Shape.
The Shape.contains() method allows a Shape
implementation to conservatively return false when:
intersect method returns true and
Shape entirely contains the rectangular area are
prohibitively expensive.
Shapes this method might
return false even though the Shape contains
the rectangular area.

The iterator for this class is multi-threaded safe, which means
that this RoundRectangle2D class guarantees that
modifications to the geometry of this RoundRectangle2D
object do not affect any iterations of that geometry that
are already in process.at - an optional AffineTransform to be applied to
the coordinates as they are returned in the iteration, or
