Constructors

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

Methods

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
