public abstract class Dimension2D extends Object implements Cloneable
TheDimension2Dclass is to encapsulate a width and a height dimension.This class is only the abstract superclass for all objects that store a 2D dimension. The actual storage representation of the sizes is left to the subclass.

clone
public Object clone()
Creates a new object of the same class as this object.- Overrides:
-
clonein classObject - Returns:
- a clone of this instance.
