Java Application to implement Caesar’s Cipher Encryption
Write a Java application to implement the following:
The cipher that Caesar used is a simple shift technique to replace each letter of the alphabet with another letter further down the alphabet as shown (similarly for lower case letters).
Original letter: A B C D E F G H I J K L M N O P Q R S T U V X Y Z
Coded letter: D E F G H I J K L M N O P Q R S T U V X Y Z A B C
In other words, if the letter to be encrypted is the Nth letter in the alphabet, replace it with the (N+K)th where K is some fixed Integer (Caesar used K = 3).
