Character to uni-code manipulation

Question

I'm trying to take a character to uni-code and perform some manipulations, however I am having problems converting uni-code back into a string. I've found the GetNumeric Value but cannot find the corresponding method to convert it back.
public static void main(String[] argC)
Person aPerson = new Person();
Character aCharacter;
int anInt = Character.getNumericValue('b');
System.out.println(anInt);
anInt++;
char aTempCar = anInt;
     aCharacter = new Character(aTempCar);
     System.out.println(Character.getNumericValue(aTempCar));
     System.out.println (aCharacter.toString());
}

You can convert a char to the unicode code point by casting to int. Most of the time the cast is implicit and doesn't need to be written.char character = 'b';
int codepoint = character; // = 98Similarly a code point can be converted to a char by casting but this time the casting is necessary:int codepoint = 98;
char character = (char) codepoint;You should remember that not all code points can be represented with a single char so simply casting does not give you the correct value with every code point. The [url http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Character.html#toChars(int)]Character.toChars(int) method can be used to convert a code point to characters (starting with version 1.5).
The getNumericValue() method returns you the numeric value of a character, e.g. the numeric value of '5' is 5 and the numeric value of the roman numeral 'X' is 10. It does not return the unicode code point of a character.
