acuexpert3797's honest review, Java Design Patterns course

When I was a beginner developer, when I started working and analyzed existing code, the part that I got stuck on was mostly design patterns. This lecture was a great help because it directly showed the concept and implementation method of design patterns with easy examples, which is the instructor's strength, and the lecture focused on patterns used in practice. In particular, it was great when he showed the implementation of the drawing board as a combination of the Command pattern and the Menento pattern. I think I will use it often. ^^ I will try to properly utilize design patterns in the next project. These days, when hiring developers, design patterns are always included in the preferential items. It was good to be able to learn comprehensively through this opportunity. Thank you for the great lecture.~
