Public Constructors
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 |
Public Methods
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.
Returns
true
if the objects were equal,false
otherwise
public int getHeight ()
Get the height of the size (in pixels).
Returns
- height
public int getWidth ()
Get the width of the size (in pixels).
Returns
- width
public int hashCode ()
public static Size parseSize (String string)
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:
"widthx
height" 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 |
public String toString ()
Return the size represented as a string with the format "WxH"
Returns
- string representation of the size
