Thank you for your excellent work on the topic! I have a small suggestion that could enhance your discussion on inheritance. You might consider including a note about the @Override annotation. It ensures that the compiler checks whether the method signature matches that of a method in the superclass, which helps catch errors caused by typos in superclass method names.

By incorporating this point, you can further highlight how @Override contributes to code reliability and reduces potential bugs. I hope this suggestion is helpful, and I look forward to seeing more of your content!
