I understand you want to add the int value 5 (or any other digit value) to each
character in the String to be encoded?

kind regards,

Well your going to need 2 functions. An encoding function and a decoding function. You are going to have to find a way to add an integer to a string (using scanner class to get the user input might help you on this).

Your encode function you are obviously adding 5 to each character in the string, so your decode function will naturally do the opposite (subtraction).
