Should be structured like so:

Assignment |--- problem1 |--- src |--- Encrypter.java |--- Decrypter.java |--- Application.java requirements:

The main method encrypts the user's value using Encrypter.encrypt

The main method prints the encrypted value to standard output

The main method decrypts the user's value using Decrypter.decrypt

The main method prints the decrypted value to standard output

F) Problem 1 A company that wants to send data over the Internet has asked you to write a program that will encrypt it so that it may be transmitted more securely. All the data is transmitted as four-digit integers. Your application should read a four-digit integer entered by the user and encrypt it as follows: Replace each digit with the result of adding 7 to the digit and getting the remainder after dividing the new value by 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then print the encrypted integer. Your application should also allow the user to enter an encrypted four-digit integer and then decrypt it (by reversing the encryption scheme) to form the original number
