Haha... I didn't understand anything when I first listened! But then I realized that coding lectures are about listening for 10 minutes, then spending 2 hours reviewing, struggling, and creating examples... To be honest, I still don't really get it, but I'm finding meaning in knowing more than I did before. I hope you all are happy too~!!!

It was great to quickly learn the core concepts. It's also excellent for review purposes.

good

I understood JPA simply as a tool for mapping databases and Java objects, but through this course, I feel like I've truly grasped it.

You seem to explain things in a way that's both concise and clear.

Thank you.

I had difficulties writing test code while working on projects. I feel like I've grown a lot in terms of test code while taking the course. Thank you for the great lecture.

This is a lecture that made me think deeply about how I should build my career going forward.

Your explanations are so clear that the content really sinks in. I think this will be very helpful.

The theory and practical examples were appropriately mixed, making it easy to understand, and the usage scenarios for each pattern were clear, so it seems like they can be directly applied in practice. I recommend this to those who want to systematically learn design patterns!
