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

getWidth
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
Dimension. - Since:
- 1.2
-
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
public 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()
-
setSize
public 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 thisDimensionobject- Since:
- 1.1
- See Also:
getSize(),Component.setSize(int, int)
-
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:
getSize(),Component.setSize(int, int)
-
equals
public boolean equals(Object obj)
Checks whether two dimension objects have equal values.- Overrides:
equalsin classObject- 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
-
hashCode
public int hashCode()
Returns the hash code for thisDimension.- Overrides:
hashCodein classObject- Returns:
- a hash code for this
Dimension - See Also:
Object.equals(java.lang.Object),System.identityHashCode(java.lang.Object)
-
toString
public 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.
