PLEASE DO BOTH THESE IN JAVA ASAP

1)

Implement the encryption function

Do NOT use ANY string manipulation or arithmetic functions to implement your solution.

Test that input 0xADE1 yields ciphertext (188, 153). You may hard-code these values for testing.

2)

Implement a decryption function FOR THE Cipher

Do NOT use ANY string manipulation or arithmetic functions to implement your solution.

Test that input (188, 153) yields plaintext 0xADE1. You may hard-code these values for testing.
