The Dimension class encapsulates the width and
height of a component (in integer precision) in a single object.
The class is
associated with certain properties of components. Several methods
defined by the Component class and the
LayoutManager interface return a
Dimension object.
Normally the values of width
and height are non-negative integers.
The constructors that allow you to create a dimension do
not prevent you from setting a negative value for these properties.
If the value of width or height is
negative, the behavior of some methods defined by other objects is
undefined.

| Constructor Summary | |
Dimension()
Creates an instance of Dimension with a width
of zero and a height of zero. |
|
Dimension(Dimension d)
Creates an instance of Dimension whose width
and height are the same as for the specified dimension. |
