# Class Dimension2D

java.lang.Object
java.awt.geom.Dimension2D

All Implemented Interfaces:
  `Cloneable`

Direct Known Subclasses:
  `Dimension`

public abstract class Dimension2D extends Object implements Cloneable
The `Dimension2D` class is to encapsulate a width and a height dimension.

This class is only the abstract superclass for all objects that store a 2D dimension. The actual storage representation of the sizes is left to the subclass.

Since:
  1.2

## Constructor Details

### Dimension2D

protected Dimension2D()
This is an abstract class that cannot be instantiated directly. Type-specific implementation subclasses are available for instantiation and provide a number of formats for storing the information necessary to satisfy the various accessor methods below.

## Method Details

### getWidth

public abstract double getWidth()
Returns the width of this `Dimension` in double precision.

Returns:
  the width of this `Dimension`.
Since:
  1.2

### getHeight

public abstract double getHeight()
Returns the height of this `Dimension` in double precision.

Returns:
  the height of this `Dimension`.
Since:
  1.2

### setSize

public abstract void setSize(double width, double height)
Sets the size of this `Dimension` object to the specified width and height. This method is included for completeness, to parallel the `getSize` method of `Component`.

Parameters:
  `width` - the new width for the `Dimension` object
  `height` - the new height for the `Dimension` object
Since:
  1.2

### setSize

public void setSize(Dimension2D d)
Sets the size of this `Dimension2D` object to match the specified size. This method is included for completeness, to parallel the `getSize` method of `Component`.

Parameters:
  `d` - the new size for the `Dimension2D` object
Since:
  1.2

### clone

public Object clone()
Creates a new object of the same class as this object.

Overrides:
  `clone` in class `Object`
Returns:
  a clone of this instance.
Throws:
  `OutOfMemoryError` - if there is not enough memory.
Since:
  1.2
