PLEASE DO THIS IN JAVA. THIS IS CHARACTER DECODING.

Write a program that decrypts the output created by the program given by reversing the steps. NOTE: you won't be able to recover whitespace, punctuation symbols or original case this way!

Example:

Given an input:

0x4C 0x50 0x53 0x53 0x50 0x49 0x50 0x41 0x56 0x48

step 1. Create a new list of values in the right order

0x4c 0x49 0x50 0x50 0x53 0x41 0x53 0x56 0x50 0x48

step 2. Shift four positions to the left (mod 26)

0x48 0x45 0x4c 0x4c 0x4f 0x57 0x4f 0x52 0x4c 0x44

Step 3. Convert back to characters using UTF-8 encoding
