Interface  Description 

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. 
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. 
Arc2D 
Arc2D is the abstract superclass for all objects that
store a 2D arc defined by a framing rectangle,
start angle, angular extent (length of the arc), and a closure type
(OPEN , CHORD , or PIE ). 
Arc2D.Double 
This class defines an arc specified in
double precision. 
Arc2D.Float 
This class defines an arc specified in
float precision. 
Area 
An
Area object stores and manipulates a
resolutionindependent description of an enclosed area of
2dimensional space. 
CubicCurve2D 
The
CubicCurve2D class defines a cubic parametric curve
segment in (x,y) coordinate space. 
CubicCurve2D.Double 
A cubic parametric curve segment specified with
double coordinates. 
CubicCurve2D.Float 
A cubic parametric curve segment specified with
float coordinates. 
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 framing rectangle. 
Ellipse2D.Double 
The
Double class defines an ellipse specified
in double precision. 
Ellipse2D.Float 
The
Float class defines an ellipse specified
in float precision. 
FlatteningPathIterator 
The
FlatteningPathIterator class returns a flattened view of
another PathIterator object. 
GeneralPath 
The
GeneralPath class represents a geometric path
constructed from straight lines, and quadratic and cubic
(Bézier) curves. 
Line2D 
This
Line2D represents a line segment in (x,y)
coordinate space. 
Line2D.Double 
A line segment specified with double coordinates.

Line2D.Float 
A line segment specified with float coordinates.

Path2D 
The
Path2D class provides a simple, yet flexible
shape which represents an arbitrary geometric path. 
Path2D.Double 
The
Double class defines a geometric path with
coordinates stored in double precision floating point. 
Path2D.Float 
The
Float class defines a geometric path with
coordinates stored in single precision floating point. 
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. 
QuadCurve2D.Double 
A quadratic parametric curve segment specified with
double coordinates. 
QuadCurve2D.Float 
A quadratic parametric curve segment specified with
float coordinates. 
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. 
RoundRectangle2D.Double 
The
Double class defines a rectangle with rounded
corners all specified in double coordinates. 
RoundRectangle2D.Float 
The
Float class defines a rectangle with rounded
corners all specified in float coordinates. 
Exception  Description 

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. 
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.
