I have some serious questions here - for example polymorphism is totally wrong, you showed just overloaded methods, it's absolutely has nothing in common with polymorphism. Polymorphism here would be when you will have parent and child classes having method with the SAME signature but doing absolutely different stuff.

It's a vey nice tutorial, thank you so much!
