public static Size parseSize(java.lang.String string) throws java.lang.NumberFormatException
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
