OOP Java for the AP CompSci A Test Starting Code: import java.util.Scanner; /** * Simple Polyalphabetic Cryptography * * @Chris Thiel * @28 Feb 2009 */ public class VignereCipherStartingCode { private static final String alphabet="ABCDEFGHIJKLMNOPQRSTUVWXYZ"; private static int nextChar(String k, int i){ i=i%k.length(); String letter=k.substring(i,i+1); return alphabet.indexOf(letter); } public static String encode (String m, String k){ String result=""; for (int i=0; i<m.length(); i++){ int offset=nextChar(k, i); String letter = m.substring(i,i+1); int newLetterIndex= alphabet.indexOf(letter)+offset; newLetterIndex=newLetterIndex % 26; result+=alphabet.substring( newLetterIndex, newLetterIndex+1); } return result; } public static String decode (String m, String k){ String result=""; return result; } public static void main(String[] args) { Scanner kb=new Scanner(System.in); System.out.print("Type a key: "); String key=kb.nextLine(); key=key.toUpperCase(); key=key.replace(" ","");//omit spaces System.out.print("Type a message: "); String message=kb.nextLine(); message=message.toUpperCase(); message=message.replace(" ",""); System.out.println("Using the key \""+key+"\" on \""+message+"\":"); String codedMessage=encode(message,key); System.out.println("Coded="+codedMessage); System.out.println("Decoded="+decode(codedMessage,key)); } } * 8 points: Complete the decode method so it can decipher the Vignere Cipher * 9 points: Adapt this so it can do a Progressive Polyalphabetic Cipher rather than a key * 10 points: Adapt the CarTalk Employee Applet's graphic user interface so that you can type a message in one text area, press a button and it shows the encoded text (using the Progressive Cipher), press another button and it shows the decoded text. * 11 points: Add a "key field" to the Applet, and use the Vignere Cipher, working in a similiar fashion as the 10 point version
