It seems like a class where you can properly learn the basic theory under the concept of object orientation. It is a class that conceptually explains and repeatedly instills the content that you must learn and become familiar with to the point that you can think of modern programming languages as object orientation, so you may feel bored, but rather than that, you will feel the impression that you can properly understand the fundamentals. I hope the instructor will continue to make other lectures like this in the future. This is a course where you can perfectly learn about object orientation through Java, even if it is not Java. I highly recommend it.
