Class  Description 

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. 
Dimension2D 
The
Dimension2D class is to encapsulate a width
and a height dimension. 
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. 
Rectangle2D 
The
Rectangle2D class describes a rectangle
defined by a location (x,y) and dimension
(w x h) . 
RectangularShape 
RectangularShape is the base class for a number of
Shape objects whose geometry is defined by a rectangular frame.

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. 
Path2D 
The
Path2D class provides a simple, yet flexible
shape which represents an arbitrary geometric path.

The
Float class defines a geometric path with
coordinates stored in single precision floating point.
