 is scheduled for introduction in Java

version 1.1, either as defined here, or updated for Unicode 2.0; see  20.5. In previ

20.5.24

public static char forDigit(int digit, int radix)

Returns a character that represents the given digit in the specified radix. If the

value of

radix

 is not a valid radix, or the value of

digit

 is not a valid digit in the

specified radix, the null character

 \u0000 

 is returned.

A radix is valid if and only if its value is not less than

Character.MIN_RADIX

( 20.5.3) and not greater than

Character.MAX_RADIX

 ( 20.5.4).

A digit is valid if and only if it is nonnegative and less than the

radix

.

If the digit is less than

10

, then the character value

 0 +digit

 is returned;

otherwise,

 a +digit 10

 is returned. Thus, the digits produced by

forDigit

, in

increasing order of value, are the ASCII characters:

0123456789abcdefghijklmnopqrstuvwxyz

(these are

 \u0030 

 through

 \u0039 

 and

 \u0061 

 through

 \u007a 

). If

uppercase letters are desired, the

toUpperCase

 method may be called on the

result:

Character.toUpperCase(Character.forDigit(digit, radix))
