I feel difficulty in the topics "More on Classes" and "Inheritance and Polymorphism" in Java and other languages

Question

Can anybody help me

Answer 1

You'd probably have better luck asking in the comment sections of the lessons you're having trouble with. You should be able to access them by opening the lesson, scrolling to the bottom, and hitting "view comments" or something similar to that. It would also let you narrow the question down without having to explain the entire situation.

Thanks
Actually I was asking my friend @ designing about it.
I just reminded him.
