public class Dimension extends Dimension2D implements Serializable
TheDimension
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 theComponent
class and theLayoutManager
interface return aDimension
object.Normally the values of
width
andheight
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 ofwidth
orheight
is negative, the behavior of some methods defined by other objects is undefined.- Since:
- 1.0
