Written in java

May I please get java code that uses the scanner to prompt for a 4-digit number and encrypts 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 a separate java code that prompts for an encrypted 4-digit number and decrypts it by reversing the encryption scheme used for the first java code.
