File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file modifying the data into a code, and then writing the coded contents out to a second file. There are very complex encryption techniques, but for ours, will use a simple one from the shift category. We will take each character and shift it one place in the Unicode sequence. So a becomes b, b becomes c, etc. What about z? You could make it a or just the next Unicode character, which is the choice we will take. NOTE: you must be writing and reading a text file, not a serializable one, and you must have a FileDialog ox where the user can choose the file to utilize.

Write a program names EncryptDecrypt.java that has the following menu choices:

Read in a file

Print the file to the console (obviously this is for debugging only)

Encrypt the file and write it to the console

Write out the encrypted file to a text file

Clear the data in memory

Read in an encrypted file

Decrypt the file

Write out the decrypted file to the console

End
