public class Dimension extends Dimension2D implements Serializable
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 and Description |
|---|
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. |
| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(Object obj)
Checks whether two dimension objects have equal values.
|
double |
getHeight()
Returns the height of this
Dimension in double
precision. |
Dimension |
getSize()
Gets the size of this
Dimension object. |
double |
getWidth()
Returns the width of this
Dimension in double
precision. |

Sets the size of this
Dimension object to the specified size. |
void |
setSize(double width,
double height)
Sets the size of this
Dimension object to
the specified width and height in double precision. |
void |
setSize(int width,
int height)
Sets the size of this
Dimension object
to the specified width and height. |
