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.
Component, LayoutManager, Serialized Formpublic int width
The width dimension; negative values can be used.
getSize(), setSize(double, double)
public int height
The height dimension; negative values can be used.
getSize(), setSize(double, double)
public Dimension()
Creates an instance of Dimension with a width of zero and a height of zero.
public Dimension(Dimension d)
Creates an instance of Dimension whose width and height are the same as for the specified dimension.
d - the specified dimension for the width and height valuespublic Dimension(int width,
int height) Constructs a Dimension and initializes it to the specified width and specified height.
width - the specified widthheight - the specified heightpublic double getWidth()
Returns the width of this Dimension in double precision.
getWidth in class Dimension2D
Dimension.public double getHeight()
Returns the height of this Dimension in double precision.
getHeight in class Dimension2D
Dimension.public void setSize(double width,
double height) Sets the size of this Dimension object to the specified width and height in double precision. Note that if width or height are larger than Integer.MAX_VALUE, they will be reset to Integer.MAX_VALUE.
setSize in class Dimension2D
width - the new width for the Dimension objectheight - the new height for the Dimension objectpublic Dimension getSize()
Gets the size of this Dimension object. This method is included for completeness, to parallel the getSize method defined by Component.

public void setSize(Dimension d)
Sets the size of this Dimension object to the specified size. This method is included for completeness, to parallel the setSize method defined by Component.
d - the new size for this Dimension objectgetSize(), Component.setSize(int, int)
public void setSize(int width,
int height) Sets 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.

public boolean equals(Object obj)
Checks whether two dimension objects have equal values.
equals in class Object
obj - the reference object with which to compare.true if this object is the same as the obj argument; false otherwise.Object.hashCode(), HashMap
public int hashCode()
Returns the hash code for this Dimension.
hashCode in class Object

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
public 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.
