It might be difficult if you hear it without any prior knowledge, but it seems to be very helpful if you briefly go through it and practice.

This lecture is a great lecture for those who have studied Java to some extent and are getting into lambda expressions, rather than those who are just starting out with Java. I didn't know how to use it while doing a project, and I was using stream and lambda expressions for the first time, so I couldn't understand it no matter how much I looked it up, and I was frustrated, but I finally found out about this sweet lecture that can be finished in just one hour... I watched it, and it hasn't been that long since the lecture came out. This is my first time leaving a review while listening to the lecture. The reason I didn't understand lambda expressions and streams is because I didn't understand the process for the code to change like this, but I understood it so well because you received an interface as a parameter, inherited it, and showed the result. Thank you.

      Devic's review makes me feel so happy🚀✨✨ When I was putting together this course, I had two goals. One was to help you organize what you learned, and the other was to help those who are just starting out study more easily later on. I'm so happy to hear that it helped you build a foundation! I'll be back with an even better course in the future! 💝

      Tititi, thank you so much for your review! I tried to pack as much content as possible into the limited time of 1 hour, and I'm so glad you were able to learn so much~😊I was worried at first whether this concept would resonate with the students, but I'm so glad to receive such positive feedback. Thank you again for your valuable review.
