CIT 130 PROGRAM 3 SPRING 2021 For this assignment you will write a program that reads and writes to text files. Once you are able to read and write text files, add code to encode and decode messages using the Baconian cipher. This cipher was developed by English statesman and philosopher Francis Bacon. It works by replacing a letter with a sequence of five A's and/or B's. As documented in the above website, this is the table for encoding/decoding by the Baconian cipher. tr. a b 5 t t BABBA BABBB n Z i AABSA AAB35 A.BAAA BBBMA ABAAB ABABA AAAAS AAABA AAAB3 AABAA PARA ABABB ABBAR ABBAS ABBBA ABPB 3 BAAAB BAABA BAABB BBBAB BAPAA BARAB al e f V w k 1 r X c 0 Requirements: Create either a GUI or use a menu based application to enter the filename(s) and text to encrypt. Your application should allow the user to select to encrypt or decrypt as many messages as they like. Javadoc your class (your application) and all methods. In particular, I want you to use the following Javadoc tags: o @author @param @return o @throws c@version Code at least three methods (I used five) using the process of functional decomposition described in Chapter 5 of our text. Other Unicode characters are to be left as "plain text"; they are not encoded. Try coding encrypting text first, after reading and writing files Hints: I used the StringTokenizer class to decode my "secret message". Look at methods of the String class; these methods may be useful: o split (this is one of the preferred methods to break apart a String now rather than StringTokenizer - it places each separate "word" into an array, so if you aren't comfortable with arrays, I'd stick with StringTokenizer) o toUpperCase c substring cindexOf I also used StringBuffer which allows you to really append things to a "String-like" object. If you know how to manipulate arrays, feel free to use arrays. If you use arrays, you don't need to use the substring and indexOf methods of the String class. I also added a space(blank) after each encrypted character in the text file so I could use the StringTokenizer class. I converted everything to upper case (just for convenience). You don't have to use any of my hints if you can find another way to solve this problem.
