Changed Classes and Interfaces 
AffineTransform

The AffineTransform class represents a 2D affine transform that performs a linear mapping from 2D coordinates to other 2D coordinates that preserves the "straightness" and "parallelness" of lines. 
Area

The Area class is a deviceindependent specification of an arbitrarilyshaped area. 
CubicCurve2D

The CubicCurve2D class defines a cubic parametric curve segment in (x y) coordinate space. 
Dimension2D

The Dimension2D class is to encapsulate a width and a height dimension. 
Ellipse2D

The Ellipse2D class describes an ellipse that is defined by a bounding rectangle. 
GeneralPath

The GeneralPath class represents a geometric path constructed from straight lines and quadratic and cubic (Bézier) curves. 
IllegalPathStateException

The IllegalPathStateException represents an exception that is thrown if an operation is performed on a path that is in an illegal state with respect to the particular operation being performed such as appending a path segment to a GeneralPath without an initial moveto. 
Line2D

This Line2D represents a line segment in (x y) coordinate space. 
NoninvertibleTransformException

The NoninvertibleTransformException class represents an exception that is thrown if an operation is performed requiring the inverse of an AffineTransform object but the AffineTransform is in a noninvertible state. 
PathIterator

The PathIterator interface provides the mechanism for objects that implement the Shape interface to return the geometry of their boundary by allowing a caller to retrieve the path of that boundary a segment at a time. 
Point2D

The Point2D class defines a point representing a location in (x y) coordinate space. 
Point2D.Double

The Double class defines a point specified in double precision. 
Point2D.Float

The Float class defines a point specified in float precision. 
QuadCurve2D

The QuadCurve2D class defines a quadratic parametric curve segment in (x y) coordinate space. 
Rectangle2D

The Rectangle2D class describes a rectangle defined by a location (x y) and dimension (w x h). 
Rectangle2D.Double

The Double class defines a rectangle specified in double coordinates. 
Rectangle2D.Float

The Float class defines a rectangle specified in float coordinates. 
RectangularShape

RectangularShape is the base class for a number of Shape objects whose geometry is defined by a rectangular frame. 
RoundRectangle2D

The 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.
