Design Patterns in Java (Udemy.com)

This course helped me to understand better the design patterns and to enrich my knowledge with the names and the approaches I use in my coding. It would be better to have some UML drawings, just to understand schema for the dependencies which would help for consistent understanding of the changes and going back and forth during the presentation. Otherwise, I would say that the course is great and very good English and pronunciation. Спасибо Дмитри! Всего хорошего!

I would find the material even more effective if the explanations progressed in two ways: first, from high-level conceptual representations, as you already did, and in a visual format such as diagrams, toward concrete implementations; and second, from low to higher levels of complexity, starting with simple, real life examples and gradually moving to more advanced ones. I really appreciate the coding exercises and the effort put into the course.

Great course! Dmitri is brilliant and obviously very well-versed in the material. My only slight dislike was the coverage of the Adapter pattern, as it felt like too much time and effort was spent propping up the implementation of the example (rendering lines in vector objects from points) and its hashCode() and toSpring() implementations, to the point where the pattern became a bit of an afterthought. That notwithstanding, I'd happily take another course from Dmitri.

I thought the instruction was excellent: crisp, concise and clearly knowledgeable. The lectures had a smooth flow which exemplified strong command of the subject matter. The examples focused on clearly presenting the concepts rather than getting bogged down in real-world complexity. At the same time, the applications were varied in context. A few of the coding exercises were perhaps more complex than needed, but overall, they related to the subject material. I really appreciated the nuances of some of the alternative approaches. I enjoyed the content and would recommend it to friends.

Wrote my last JavaCode 3 years ago when i was studying. Thought i'd have a hard time recapping all of that in a 10h course, but everything is explained very well and detailled. The instructor repeats important patterns while teaching new ones, so it's pretty hard to not take everything into account learned from the lessons before. Exercises will firm the knowledge acquired. Awesome!

This is an amazing course. The instructor is very knowledgeable about design patterns. What comes across in particular is his clarity of thought in both his coding and ability to express ideas; quite IMPRESSIVE really. The course content is very condensed. The instructor doesn't mince his words and goes straight to the point, which means that you feel you get much more than the 10.5 hours advertised! Some of the reviewers complain about the rapid speed of the instructor's delivery, but I don't mind that at all. He keeps things going at a good pace, and you can always rewind if needed. Another plus is that you get more than 'design patterns' out of the course. There are a lot of 'unspoken' lessons that I have learned by rereading through his code and solutions to the exercises. His use of 'modern' Java features was very welcome to the learning experience, given I am new to the language. I really struggled taking off half a star, but the reasons I did that is that the instructor set the bar so high with his delivery and approach. The two niggles I had were: a) once in a while, he pastes some extra code in a lesson. Most of the times, that extra is minimal, but once in a while, the addition is a large chunk that remains unexplained, which distracts from grasping the pattern being taught; b) sometimes, the exercise directions are not clear (the test files help with hints). In summary: highly recommended.

Dmitri really masters design patterns and maybe this turn him so confident to speak so quickly explaining the concepts. It's so hard for the beginner to stick up with him without getting lost along the way. Maybe it's not his fault, maybe design patterns is confusing for the beginners. Also I think it might help to have more illustrations with real examples to support the introduction of each pattern. I recommend to visit Refactoring dot Guru Website to get some ideas.

Learning new things. Teaching with examples rather than just slides makes it much easier to understand as well.

Examples are very complex to understand.

I love the presentation, but I type very slow.

This is indeed a very good design pattern course as it explains GoF's idea of Design Patterns nicely.

I like the way everything is summarised in each section. Very useful for quick revision.
