 public class Dimension extends Dimension2D implements Serializable TheDimensionclass 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 theComponentclass and theLayoutManagerinterface return aDimensionobject.Normally the values of widthandheightare 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 ofwidthorheightis negative, the behavior of some methods defined by other objects is undefined.- Since:
- 1.0

Method Detail- 
getWidthpublic double getWidth() Returns the width of thisDimensionin double precision.- Specified by:
- getWidthin class- Dimension2D
- Returns:
- the width of this Dimension.
- Since:
- 1.2
 
 - 
getHeightpublic double getHeight() Returns the height of thisDimensionin double precision.- Specified by:
- getHeightin class- Dimension2D
- Returns:
- the height of this Dimension.
- Since:
- 1.2
 
 - 
setSizepublic 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 class- Dimension2D
- Parameters:
- width- the new width for the- Dimensionobject
- height- the new height for the- Dimensionobject
- Since:
- 1.2
 
 - 
getSizepublic Dimension 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(double, double),- Component.getSize()
 
 - 
setSizepublic void setSize(Dimension d) 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 this- Dimensionobject
- Since:
- 1.1
- See Also:
- getSize(),- Component.setSize(int, int)
 
 - 
setSizepublic 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 this- Dimensionobject
- height- the new height for this- Dimensionobject
- Since:
- 1.1
- See Also:
- getSize(),- Component.setSize(int, int)
 
 - 
equalspublic boolean equals(Object obj) Checks whether two dimension objects have equal values.- Overrides:
- equalsin class- Object
- Parameters:
- obj- the reference object with which to compare.
- Returns:
- trueif this object is the same as the obj argument;- falseotherwise.
- See Also:
- Object.hashCode(),- HashMap
 
 - 
hashCodepublic int hashCode() Returns the hash code for thisDimension.- Overrides:
- hashCodein class- Object
- Returns:
- a hash code for this Dimension
- See Also:
- Object.equals(java.lang.Object),- System.identityHashCode(java.lang.Object)
 
 - 
toStringpublic String 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.
