Constructor Detail

Size

public Size(int width,
            int height)

Create a new immutable Size instance.

Parameters:

width - The width of the size, in pixels

height - The height of the size, in pixels

Method Detail

getWidth

public int getWidth()

Get the width of the size (in pixels).

Returns:

width

getHeight

public int getHeight()

Get the height of the size (in pixels).

Returns:

height

equals

public boolean equals(Object obj)

Check if this size is equal to another size.

Two sizes are equal if and only if both their widths and heights are equal.

A size object is never equal to any other type of object.

Overrides:

equals in class Object

Parameters:

obj - the object to compare this instance with.

Returns:

true if the objects were equal, false otherwise

See Also:

Object.hashCode()

toString

public String toString()

Return the size represented as a string with the format "WxH"

Overrides:

toString in class Object

Returns:

string representation of the size

parseSize

public static Size parseSize(String string)
                      throws NumberFormatException

Parses the specified string as a size value.

The ASCII characters \u002a ('*') and \u0078 ('x') are recognized as separators between the width and height.

For any Size s: Size.parseSize(s.toString()).equals(s). However, the method also handles sizes expressed in the following forms:

"widthxheight" or "width*height" => new Size(width, height), where width and height are string integers potentially containing a sign, such as "-10", "+7" or "5".

 Size.parseSize("3*+6").equals(new Size(3, 6)) == true
 Size.parseSize("-3x-6").equals(new Size(-3, -6)) == true
 Size.parseSize("4 by 3") => throws NumberFormatException
 

Parameters:

string - the string representation of a size value.

Returns:

the size value represented by string.

Throws:

NumberFormatException - if string cannot be parsed as a size value.

NullPointerException - if string was null

hashCode

public int hashCode()

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Overrides:

hashCode in class Object

Returns:

this object's hash code.
