Java Application - CaesarCipher

Java Application - CaesarCipher In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption.  There are many algorithms that have been invented. A Caesar Cipher is a very simple technique.  The algorithm is named after Julius Caesar who used it in some of his correspondence. The algorithm transforms normal text by shifting each letter a certain number of characters either to the left or the right.  The shift direction and count is known as the key. Example 1:  Key is -3 (shift left 3) Example 2:  Key is +3 (shift right 3) Here is a URL for a site that allows you to test the algorithm http://www.xarg.org/tools/caesar-cipher/ Notice that the case of the original text is maintained and that non-letters are not encrypted. Create a java application to prompt the user for a key and a phrase.  After the information is entered, encrypt the phrase using the provided key. Validate the key.  The absolute value of the key cannot be less than 1 or greater than 25.  Prompt the user in a loop until a valid key is entered. Put the code in a loop to continue prompting for more keys and phrases to encrypt.
