public static String toLowerCase ( String str ) { int len = str . length ( ) ; char c ; for ( int i = 0 ; i < len ; i ++ ) { c = str . charAt ( i ) ; if ( ! ( ( c >= 'a' && c <= 'z' ) || ( c >= '0' && c <= '9' ) ) ) { return str . toLowerCase ( ) ; } } return str ; }
cast a string a lower case String is faster than the String . toLowerCase if all Character are already Low Case
