Coding and explaining a basic program for Java intro course

Hey guys, I need some help to manage to finish this little Java introduction course project. The task is attached and also accessible on the link below. Since this is a very basic coding project, its more about explaining line by line what you are doing as you would to an introduction java programmer. This should be one word page with approximately 750 words. Please program in very basic and organised java since the idea of this project is to show beginners how this code works. One attached file explains everything to chapter 9 which the students already know.

Price negotiable

Deadline is this Tuesday evening at 8 pm CET.
