Examples of java.awt.geom.Rectangle2D

java.awt.geom.Rectangle2D
The Rectangle2D class describes a rectangle defined by a location {@code (x,y)} and dimension {@code (w x h)}.
This class is only the abstract superclass for all objects that store a 2D rectangle. The actual storage representation of the coordinates is left to the subclass. @version 1.32, 02/24/06 @author Jim Graham @since 1.2
