How to practice a codes on desired concept

I want to practice inheritance concept codes in Java. But I am not able find it out. I would be much obliged if I am directed on how to do it.

You can find content and problems on inheritance in Java here - Learn Advanced Java Programming Online Practical Course - CodeChef
and here - Learn Object Oriented programming using Java - CodeChef.

Whenever you want to find a concept, just go to Learn to Code - Online Coding Learning Platform - CodeChef and use the search box.

Thanks a ton. It means a lot. Happy coding!!
