publicSize(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

Public Methods

public booleanequals(Objectobj)

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.

Returns
  • trueif the objects were equal,falseotherwise

public intgetHeight()

Get the height of the size (in pixels).

Returns
  • height

public intgetWidth()

Get the width of the size (in pixels).

Returns
  • width

public inthashCode()

public staticSize parseSize(Stringstring)

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 anySize 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), wherewidthandheightare 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 bystring.
Throws
NumberFormatException ifstringcannot be parsed as a size value.
NullPointerException ifstringwasnull

publicStringtoString()

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

Returns
  • string representation of the size
