public abstract class Line2D extends Object implements Shape, Cloneable
Line2D represents a line segment in (x,y)
coordinate space. This class, like all of the Java 2D API, uses a
default coordinate system called user space in which the y-axis
values increase downward and x-axis values increase to the right. For
more information on the user space coordinate system, see the
Coordinate Systems section of the Java 2D Programmer's Guide.
This class is only the abstract superclass for all objects that store a 2D line segment. The actual storage representation of the coordinates is left to the subclass.
