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.

public double getWidth()Returns the width of thisDimensionin double precision.- Specified by:
getWidthin classDimension2D- Returns:
- the width of this
Dimension. - Since:
- 1.2
-
getHeight
public double getHeight()Returns the height of thisDimensionin double precision.- Specified by:
getHeightin classDimension2D- Returns:
- the height of this

setSize
public void setSize(double width, double height) Sets the size of thisDimensionobject to the specified width and height in double precision. Note that ifwidthorheightare larger thanInteger.MAX_VALUE, they will be reset toInteger.MAX_VALUE.- Specified by:
setSizein classDimension2D- Parameters:
width- the new width for theDimensionobjectheight- the new height for theDimensionobject- Since:
- 1.2
-
getSize
Gets the size of thisDimensionobject. This method is included for completeness, to parallel thegetSizemethod defined byComponent.- Returns:
- the size of this dimension, a new instance of
Dimensionwith the same width and height - Since:
- 1.1
- See Also:
-
setSize
Sets the size of thisDimensionobject to the specified size. This method is included for completeness, to parallel thesetSizemethod defined byComponent.- Parameters:
d- the new size for thisDimensionobject- Since:
- 1.1
- See Also:
-
setSize
public void setSize(int width, int height) Sets the size of thisDimensionobject to the specified width and height. This method is included for completeness, to parallel thesetSizemethod defined byComponent.- Parameters:
width- the new width for thisDimensionobjectheight- the new height for thisDimensionobject- Since:
- 1.1
- See Also:
-
equals
Checks whether two dimension objects have equal values. -
hashCode
public int hashCode()Returns the hash code for thisDimension. -
toString
Returns a string representation of the values of thisDimensionobject'sheightandwidthfields. 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.
