SOLID Principles of Object Oriented Design and Architecture (Udemy.com)

The explanations are good but i think some parts repeat to often while others are too abstract. The LSP specifically could use some touch up to make the covariance of return and contravariance of parameters more clear. The UML helps a bit but concrete examples with a bit of code could help understand that concept more i think. For example if someone is expecting a pizza its okay to return a vegan pizza but its not okay to return italian food in general because that might include pasta (covariance of return). If your staff delivers italian food but one of the drivers only accepts pizza then thats bad as well (contravariance of parameters). Something like that. Pronunciation can be tricky as well but i think with good understanding of english this is not as big of a problem. Overall thank you so much for investing the time, i really enjoyed the course!

Previously, I only understood SOLID at a theoretical level and tried to apply it without fully grasping the underlying reasons. This course has provided tremendous value—not only by helping me build a correct mindset, but also by offering well-analyzed, practical examples that demonstrate how to apply these principles in real-world scenarios, including situations where they should not be applied. Thank you very much.

It is a rare case that the author provides information when to NOT apply the new knowledge / pattern. It is actually a question I do ask during internal trainings, as over the years I have observed that many people, often very intelligent, follow rules blindly without deep understanding, starting with scrum as a prime example and ending with programming principles, kind of Cargo Cult Programming / Law of the Instrument mixture.

I've been hearing about SOLID principles for a long time now. After reading a few Wikipedia or blog pages about this topic, I decided to follow a proper course. And I'm not disappointed! I can say with confidence this is one the best courses I have ever taken since the end of my IT studies. Now that I know better about SOLID, I feel that every IT student should be told about those principles and I would have liked to learn them during my studies. Great job!

I have been a Java developer for the last 10 years. However, most of the times I have worked with legacy code. After having completed this course, I realize that I have doing some things in many ways that break the SOLID principles. The concepts and details explained here gave me a truly new perspective about how I should code from now on. I am very grateful for all the knowledge I have received from this course! I definitely recommend it!

Thanks Vasiliy for this SOLID course, I think it's a fundamental programming knowledge that better to be known by everybody ! Now, I understand SOLID better. In my opinion, after you got new info, it needs some time and practice to give your brain to create strong connections between neurons to get insights, so let me take this time ) !!!

This course is amazing because it's a summary and more for SOLID. I knew nothing about it before starting this course and I feel I learned a lot. However, one thing I didn't like was that the last 2 principles were not explained really well (in my opinion), so I had to research on internet in order to understand. I think the examples in these 2 section could have been better. Other than that, I recommend this course!

I have known SOLID before but never really applied it appropriately and have misused it as well. It is very easy to develop a primitive or partial understanding of it. This course has made me understand the philosophy behind SOLID and its effective use and I constantly use it as a quick reference. Instructor has condensed his learnings from multiple popular authors, contributors, papers and his own experience into this course. For all the lazy people who have avoided reading popular technical books on the subject - start with this and maybe it'll even get you reading as well.

Yes.

Grundstzlich hatte ich gehofft, dass etwas mehr in Quellcode zu sehen sei und mehr praktische Beispiele im Detail zu sehen wren. Alledings muss gestehen, dass der Kurs dies gar nicht bentigt hat und die Prizipien sehr gut mit wenig Code und UML Diagrammen funktioniert hat. Der Kurs war fr mich interessant und hilfreich.
Man lernte etwas ber die historischen Hintergrnde, Hinweise zur praktischen Anwendung und auch Informationen ber mgliche Fallstricke, wo man die Prinzipien vielleicht besser nicht anwendet.
Ich fand das Temo und die Art der Prsentation sehr gut und natrlich den Kontent ebenso.
Jeder hat andere Vorstellungen, aber ich wr positiv berrascht und bin voll zufrieden mit dem Kurs.
Vielen Dank also fr die Gute Arbeit und fr das Teilen der Erfahrungen und des Wissens.
Daumen hoch und weiter so....ich mag nichts anders als 5 Sterne geben :-)

nice course.

Great course
