Class Dimension

- - java.awt.Dimension

All Implemented Interfaces:: Serializable, Cloneable

Direct Known Subclasses:: DimensionUIResource

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.

Since:: 1.0

Field Detail

width

public int width

The width dimension; negative values can be used.

Since:: 1.0
See Also:: getSize(), setSize(double, double)

height

public int height

The height dimension; negative values can be used.

Since:: 1.0
See Also:: getSize(), setSize(double, double)

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; height - the specified height

Method Detail

getWidth

public double getWidth()

Returns the width of this Dimension in double precision.

Specified by:: getWidth in class Dimension2D
Returns:: the width of this Dimension.
Since:: 1.2

getHeight

public double getHeight()

Returns the height of this Dimension in double precision.

Specified by:: getHeight in class Dimension2D
Returns:: the height of this Dimension.
Since:: 1.2

setSize

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.

Specified by:: setSize in class Dimension2D
Parameters:: width - the new width for the Dimension object; height - the new height for the Dimension object
Since:: 1.2

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:: 1.1
See Also:: setSize(double, double), Component.getSize()

setSize

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.

Parameters:: d - the new size for this Dimension object
Since:: 1.1
See Also:: getSize(), Component.setSize(int, int)

setSize

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.

Parameters:: width - the new width for this Dimension object; height - the new height for this Dimension object
Since:: 1.1
See Also:: getSize(), Component.setSize(int, int)

equals

public boolean equals(Object obj)

Checks whether two dimension objects have equal values.

Overrides:: equals in class Object
Parameters:: obj - the reference object with which to compare.
Returns:: true if this object is the same as the obj argument; false otherwise.
See Also:: Object.hashCode(), HashMap

hashCode

public int hashCode()

Returns the hash code for this Dimension.

Overrides:: hashCode in class Object
Returns:: a hash code for this Dimension
See Also:: Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

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.

Overrides:: toString in class Object
Returns:: a string representation of this Dimension object
