The lecture content was a bit disappointing. I thought it would be a practical code that could be used right away in practice, but it was a bit disappointing.
Also, while the beginning was written step by step, from the middle to the latter part, it was a bit disappointing that it just
pasted the source code and gave a rough explanation.
It would have been better to understand if it had been written step by step, but
since it was too fast to paste the code and explain it, I missed a lot of parts and had to go back and look at them.
However, for those who lack the basics or do not have a basic understanding of design patterns,
I think they will get the feeling that this pattern is implemented this way.
Anyway, it is an overall disappointing lecture with poor quality.
I bought a book to study design patterns and watched YouTube lectures, but this was more helpful for my understanding.
I like the part where each pattern is explained step by step.
However, not all the pattern explanations were like that.
I took off one star because I had high expectations after reading the lecture introduction.
I agree with Freelife's lecture evaluation.
I tried to study design patterns by reading books and looking for lectures...
I finally found a lecture that I like..
Overall, it was well organized, and most of all, I liked the examples.
It's not easy to provide sufficient understanding with short example sources, but I could feel that a lot of effort was put into it.
Thank you for the great lecture..I think it would be helpful for other developers to listen to it once.^^
I had a vague feeling about design patterns, but through this lecture, I was able to easily understand frequently used design patterns. I recommend it to those who are curious about Java-based design patterns~
