Class Dimension
- Cloneable, Serializable
This class holds a width and height value pair. This is used in plenty
of windowing classes, but also has geometric meaning.
It is valid for a dimension to have negative width or height; but it
is considered to have no area. Therefore, the behavior in various methods
is undefined in such a case.
There are some public fields; if you mess with them in an inconsistent
manner, it is your own fault when you get invalid results. Also, this
class is not threadsafe.
int | height- The height of this object.
|
int | width- The width of this object.
|
Dimension()- Create a new Dimension with a width and height of zero.
|
Dimension(int w, int h)- Create a new Dimension with the specified width and height.
|
Dimension(Dimension d)- Create a new Dimension with width and height identical to that of the
specified dimension.
|
boolean | equals(Object obj)- Tests this object for equality against the specified object.
|
double | getHeight()- Gets the height of this dimension.
|
Dimension | getSize()- Returns the size of this dimension.
|
double | getWidth()- Gets the width of this dimension.
|
int | hashCode()- Return the hashcode for this object.
|
void | setSize(double w, double h)- Sets the size of this dimension.
|
void | setSize(int w, int h)- Sets the width and height of this object to the specified values.
|
void | setSize(Dimension d)- Sets the width and height of this object to match that of the
specified object.
|
String | toString()- Returns a string representation of this object.

height
public int height
The height of this object.
width
public int width
The width of this object.
Dimension
public Dimension()
Create a new Dimension with a width and height of zero.
Dimension
public Dimension(int w,
int h) Create a new Dimension with the specified width and height.
w - the width of this objecth - the height of this object
Dimension
public Dimension(Dimension d)
Create a new Dimension with width and height identical to that of the
specified dimension.
d - the Dimension to copy
equals
public boolean equals(Object obj)
Tests this object for equality against the specified object. This will
be true if and only if the specified object is an instance of
Dimension2D, and has the same width and height.
- equals in interface Object
obj - the object to test against
- true if the object is equal to this
getSize
public Dimension getSize()
Returns the size of this dimension. A pretty useless method, as this is
already a dimension.
hashCode
public int hashCode()
Return the hashcode for this object. It is not documented, but appears
to be ((width + height) * (width + height + 1) / 2) + width.
- hashCode in interface Object
setSize
public void setSize(double w,
double h) Sets the size of this dimension. The values are rounded to int.
- setSize in interface Dimension2D
w - the new widthh - the new height
setSize
public void setSize(int w,
int h) Sets the width and height of this object to the specified values.
w - the new width valueh - the new height value
setSize
public void setSize(Dimension d)
Sets the width and height of this object to match that of the
specified object.
d - the Dimension to get the new width and height from
toString
public String toString()
Returns a string representation of this object. The format is:
getClass().getName() + "[width=" + width + ",height=" + height
+ ']'.
- toString in interface Object
- a string representation of this object
Dimension.java -- represents a 2-dimensional span
