public class Dimension extends Dimension2D implements Serializable
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.

The width dimension; negative values can be used.

The height dimension; negative values can be used.

public Dimension()
Creates an instance of Dimension
with a width of zero and a height of zero.
public Dimension(Dimension d)
Creates an instance of Dimension
whose width and height are the same as for the specified dimension.
d
- the specified dimension for the width
and height
valuespublic Dimension(int width, int height)
Constructs a Dimension
and initializes it to the specified width and specified height.

Returns the width of this Dimension
in double precision.

.public void setSize(double width, double height)
Sets the size of this Dimension
object to the specified width and height in double precision. Note that if width
or height
are larger than Integer.MAX_VALUE
, they will be reset to Integer.MAX_VALUE
.

Gets the size of this Dimension
object. This method is included for completeness, to parallel the getSize
method defined by Component
.

public String toString()
Returns a string representation of the values of this Dimension
object's height

fields. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null
