Dimension2D (Java SE 12 & JDK 12 )
Keywords: java.awt.geom.Dimension2D class

Module java.desktop
Package java.awt.geom

## 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

    `protected` | `Dimension2D()` | This is an abstract class that cannot be instantiated directly.

  - ### Method Summary

    Modifier and Type | Method | Description
    --- | --- | ---
    `Object` | `clone()` | Creates a new object of the same class as this object.
    `abstract double` | `getHeight()` | Returns the height of this `Dimension` in double precision.
    `abstract double` | `getWidth()` | Returns the width of this `Dimension` in double precision.
    `abstract void` | `setSize​(double width, double height)` | Sets the size of this `Dimension` object to the specified width and height.
    `void` | `setSize​(Dimension2D d)` | Sets the size of this `Dimension2D` object to match the specified size.

- - ### Constructor Detail

    - #### 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.

        `Dimension`

  - ### Method Detail

    - #### 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.
