Class Dimension

java.lang.Object
  |
  +--java.awt.Dimension

public class Dimension
extends java.lang.Object

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(java.lang.Object obj)
          Checks whether two dimension objects have equal values.
 Dimension getSize()
          Gets the size of this Dimension object.
 int hashCode()
          Returns the hash code for this Dimension.
 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.
 java.lang.String toString()
          Returns a string representation of the values of this Dimension object's height and width fields.

Field Detail

width

public int width
The width dimension. Negative values can be used.
See Also:
getSize(), setSize(java.awt.Dimension)

height

public int height
The height dimension. Negative values can be used.
See Also:
getSize(), setSize(java.awt.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

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.
Since:
JDK1.1
See Also:
setSize(java.awt.Dimension), Component.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.
Since:
JDK1.1
See Also:
getSize(), Component.setSize(int, int)

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.
Since:
JDK1.1
See Also:
getSize(), Component.setSize(int, int)

equals

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

hashCode

public int hashCode()
Returns the hash code for this Dimension.
Overrides:
hashCode in class java.lang.Object
Returns:
a hash code for this Dimension.

toString

public java.lang.String toString()
Returns a string representation of the values of this Dimension object's height and width 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 be null.
Overrides:
toString in class java.lang.Object
Returns:
a string representation of this Dimension object.
