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.

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. |
Dimension(int width,
int height)
Constructs a
Dimension and initializes
it to the specified width and specified height. |
