Encryptology is the process of encoding a string to another form in such a way that it should not be known to an unauthorized person. You are to encode a program in Java by using a class to encrypt a string in such a way that each character of the given string is replaced with a character at the mentioned gap (say, move). If the move is positive then the characters are replaced by other characters ahead of the given move. For a negative move, the characters are replaced by other characters backwards. In case the move is 0 then the same string is produced.
You must keep in mind that the characters are wrapped around while encryption i.e., Z is followed by A and A is followed by Z considering the moves to be negative and positive respectively.

e.g., ABZ can be encrypted as CDB if move = 2
ABZ can be encrypted as YZX if move = -2
ABZ can be encrypted as ABZ if move = 0

Class: encode
Data members/Instant variables:

String s, str

Member methods:

void input( ): To assign string st to s. Initialize String str = “”
void perform(int move): To perform encryption at a defined move
void display( ): To display the encrypted string.
