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.

Dimension
. - Since:
- 1.2
-
getHeight
public double getHeight()Returns the height of thisDimension

toString
Returns a string representation of the values of thisDimension
object'sheight
andwidth
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 benull
.
