I am a non-major who does not know Java. I am taking the Java introductory course and the basic course, and it is so easy to understand that studying has become much easier. I studied on my own, read books, and took other courses, but they felt a bit spoon-fed. However, this course helps me understand, so I studied better. In fact, studying programming languages is not all about memorizing, but I realized that I had not studied well until now. I am studying again by understanding through this course!! Non-majors who find Java difficult! I highly recommend this course!!!
