Transcribed Image Text:PROBLEM: You are to write a program in Java that takes in as input a string message and an integer. The program will then scramble the message by converting each
character of the message to its numeric code, adding the specified integer to this code, and then converting the resulting number back to a character. To do this, you must
create a class that handles a string and an encoding integer.
Required Class Variables: Should include a string to hold the message, and an int to hold the value to alter the message by.
Required Member Methods:
setMessage() - prompts the user to enter the message to be encrypted
getMessage() - lets user see what string they typed in
setCode() - prompts the user to enter the code with which to encrypt the message
getCode() - lets the user see what code they entered
encrypt() - will take in a single character at a time and return a result of type char
encryptAll() - will use a loop calling encrypt to encrypt the entire message
printOut() - prints out the converted message
To make it more readable, make sure that you skip spaces in the string (don't change them). For example, on our ASCII machines, the message:
THE REDCOATS ARE COMING!
and the integer 5 would produce:
YMJ WJIHTFYX FWJ HTRNSL&
WHAT TO HAND IN: You are to turn in a copy of your working code and screen shots of your program in action.
