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

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

 prohibitively expensive.

 return false even though the Shape contains

 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
