public static char toUpperCase( char ch )
Parameters
- ch
- the character to be converted.
Returns
the uppercase equivalent of the character, if any;
otherwise the character itself.
Description
Converts the character argument to uppercase. A character has an
uppercase equivalent if and only if an uppercase mapping is
specified for the character in the Unicode attribute table.
Note that some Unicode characters in the range
'\u2000' to '\u2000FFF' have uppercase
mappings; this method does map such characters to their titlecase
equivalents even though the method isLowerCase does
not return true for such characters.
