A Virtual Secret Decoder Ring

First, read about secret decoder rings. Then, write a class named CaeserEncryptChar that takes two arguments -- an integer representing the number of letters to shift/rotate forward, and a lower-case letter.

The output should be the encrypted version of the letter provided, under the given shift.

Sample runs:

$ java CaeserEncryptChar 3 d
$ java CaeserEncryptChar 4 x
