The basic lecture was really good because it explained things step by step so easily, so I could properly understand inheritance and polymorphism. There were many parts that I didn't understand while reading the Java book, but after listening to the teacher's lecture, I realized what parts I didn't know, and the question marks in my head turned into exclamation marks, so I enjoyed the lecture as if I was reading an interesting novel. I was able to listen to the lecture and solve the problem and review the parts I didn't know, and I was also able to learn how to code easily in IntelliJ through the explanation of the solution part. The shortcut keys in the middle of the lecture were also very useful..^^ Above all, I think it's a lecture that I don't regret spending money on because the lecture content was explained in detail step by step.. After listening to the basic lecture, Java became fun, and I'm looking forward to what else you'll teach me in the intermediate and advanced levels. I think the part where you set the lecture order was also a lecture that showed your passion for explaining things well so that students who want to build a foundation can understand it.. The teacher's lecture style of explaining things little by little is also really good..ㅎㅎㅎ If other people are looking for a Java course, I really recommend it~~!!!! This is a lecture that I want to say.. I'm so happy that you're going to do [Practical Database Roadmap] in mid-2024 after listening to the intermediate and advanced Java courses..^^ I'm always so grateful for the lectures..^^ I'll listen to the other lectures with gratitude... Thank you..^^
