int radix;  // an integer signifying the base, usually 2, 8, 10 or 16
int aDigit; // an integer for a digit ( e.g. 15 == F in Hex )

int  theValue = Character.digit    ( a, radix ); // converts char digit to integer value
char theChar  = Character.forDigit ( aDigit, radix ); // converts int value of digit to char 

// and Instance Methods

char theValue  = aCharacter.cahrValue (); // char value of Character object
String aString = aCharacter.toString ();  // String of the Character value
