Can’t understand specific cryptographic based symmetric algorithm, how to solve? [on hold]

I am working on a cryptographic based symmetric algorithm. But before that’s, I have to make software code in java for a previous proposed algorithm. The algorithm that’s i have to solve looks like:

A. Encryption Process
