public class Dimension
extends Dimension2D
implements Serializable
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.

Since:
JDK1.0
See Also:
Component, LayoutManager

Field Summary
int  height
The height dimension.
int  width
The width dimension.
 

Constructor Summary
 Dimension()
Creates an instance of Dimension with a width of zero and a height of zero.
 Dimension(Dimension d)
Creates an instance of Dimension whose width and height are the same as for the specified dimension.
 Dimension(int width, int height)
Constructs a Dimension and initializes it to the specified width and specified height.
 

Method Summary
boolean  equals(Object obj)
Checks whether two dimension objects have equal values.
double  getHeight()
Returns the height of this dimension in double precision.
Dimension  getSize()
Gets the size of this Dimension object.
double  getWidth()
Returns the width of this dimension in double precision.
void  setSize(double width, double height)
Set the size of this Dimension object to the specified width and height in double precision.
void  setSize(Dimension d)
Set the size of this Dimension object to the specified size.
void  setSize(int width, int height)
Set the size of this Dimension object to the specified width and height.
String  toString()
Returns a string that represents this Dimension object's values.

The width dimension.

height

public int height
The height dimension.
Constructor Detail

Dimension

public Dimension()
Creates an instance of Dimension with a width of zero and a height of zero.

Dimension

public Dimension(Dimension d)
Creates an instance of Dimension whose width and height are the same as for the specified dimension.
Parameters:
d - the specified dimension for the width and height values.

Dimension

public Dimension(int width,
                 int height)
Constructs a Dimension and initializes it to the specified width and specified height.
Parameters:
width - the specified width dimension
height - the specified height dimension
Method Detail

getWidth

public double getWidth()
Returns the width of this dimension in double precision.
Overrides:
getWidth in class Dimension2D

getHeight

public double getHeight()
Returns the height of this dimension in double precision.
Overrides:
getHeight in class Dimension2D

setSize

public void setSize(double width,
                    double height)
Set the size of this Dimension object to the specified width and height in double precision.
Parameters:
width - the new width for the Dimension object
height - the new height for the Dimension object
Overrides:
setSize in class Dimension2D

getSize

public Dimension getSize()
Gets the size of this Dimension object. This method is included for completeness, to parallel the getSize method defined by Component.
Returns:
the size of this dimension, a new instance of Dimension with the same width and height.
See Also:
setSize, getSize

setSize

public void setSize(Dimension d)
Set the size of this Dimension object to the specified size. This method is included for completeness, to parallel the setSize method defined by Component.
Parameters:
d - the new size for this Dimension object.
See Also:
getSize, setSize

setSize

public void setSize(int width,
                    int height)
Set the size of this Dimension object to the specified width and height. This method is included for completeness, to parallel the setSize method defined by Component.
Parameters:
width - the new width for this Dimension object.
height - the new height for this Dimension object.
See Also:
getSize, setSize

equals

public boolean equals(Object obj)
Checks whether two dimension objects have equal values.
Overrides:
equals in class Object

toString

public String toString()
Returns a string that represents this Dimension object's values.
Returns:
a string representation of this dimension, including the values of width and height.
Overrides:
toString in class Object
