I have experience learning other languages, but this is my first time learning Java, so the concept of polymorphism felt very unfamiliar. However, thanks to the way the instructor explained it step by step in each class, such as “Let’s modify it a little more here, and then modify it again,” I was able to not only understand the concept, but also directly realize why I should use it and what effect it would have. Thanks to this approach, even though this is my first time learning Java, I was able to easily understand polymorphism in a relatively short period of time. Thank you so much! The class was very helpful, and I will continue to listen to it in the future. I hope you always stay healthy!
