i'm having second thought about buying this course. Explanations are horrible and hard to understand. Seems more professional focus than beginners.

man i feel like you, but maybe it is too soon to judge... but from the scanner part everything just became worse for me and harder to grasp.

See CodeGym Articles (and the Video) for Setting and and Getting data values https://codegym.cc/groups/posts/getters-and-setters > When you see a Topic that is _new_ check out the Articles inside CodeGym. Also their are great Videos. When data is "private" in the class (the blueprint) -- how can it be accessed and modified ?

hey I just wanted to check how the assignments are getting validated. Do we have access to unit test cases so that we can understand them more clearly?

NOTE: No need to output in main method. * If a method is declared with the keyword "static", then to access the class variable, you must use "Classname.variableName". * If a method is NOT declared with the keyword "static", then to access the class variable, you must use the special keyword "this", i.e. "this.variableName".
