I recommend that you read the Java basics book on the market once and then take this class. You will be able to see how well the English teacher teaches only if you study the book by yourself while racking your brain.
Hahaha, Mr. Park Sung-geun, your hard work paid off :) Thank you^^!!

It's been almost 20 years since I developed only ERP system with development tool (Powerbuilder) not JAVA, but because of user requirements or many requests for web-based development of other systems, I needed to study for web service. I didn't know anything about JAVA or Spring, and I didn't know what kind of education I should receive, so I paid for and listened to all three lecturers' lectures on Spring. Kim Young-han is one of those three. My current progress in listening to each lecturer's lecture is 1. I have completed all of Kim Young-han's lectures except JPA. I listened to everything from basic network to introduction to Spring, backend, and DB (excluding JPA) at least twice. The reason I excluded JPA is because ERP has many complex queries, so I thought it would be more efficient to create SQL directly with MYBATIS. 2. Another instructor A's lecture had Spring 1 and 2, but I stopped halfway through the first part. The characteristic is that it focuses a lot on JSP, so it is somewhat helpful for the JSP that my company is currently using, but other than that, instead of testing it once before the lecture, there were too many problems to solve during the lecture, so it was loose. The materials were not prepared well. 3. Another instructor B's roadmap was halfway through. Although instructor B seemed to have a lot of knowledge, the lecture scenario was lacking. It was a lecture that ended in one shot rather than a linked progression, so the lack of materials was noticeable. It felt like learning short pieces of knowledge one by one rather than understanding the big picture of Spring, and there were many parts that were difficult to proceed because the Spring version was low and many objects that had already been deprecated were used. Anyway, while listening to Instructor B's lecture, JPA came up, and I thought I should go deeper into JPA, so I bought all of Kim Young-han's JPA lectures, and now that I've finished Java Intermediate 1, I'm going to proceed with JPA. While listening to Kim Young-han's lectures, I was learning Java for the first time, but I ignored Java and started right away with Spring, and it wasn't that difficult, and I was able to compare it with the development languages I had used before, and I was able to learn new things, which was really great. In addition, While listening to Spring, Backend, and DB, I searched the web for parts I didn't understand, and I was able to solve many of the questions I had at that time through this Java lecture, which was great. I feel that Kim Young-han's lectures are definitely better prepared than other lectures. From the examples used in the lectures, to the storytelling that gradually develops, and even the video editing (of course there were a lot of them. You can clearly see them as you watch the lectures), I can see the big picture with my eyes because he does a really good job.
Pet Pity, thank you for putting so much heart into your class review. It gives me great strength. I will come back with better lectures in the future :) I hope you study hard and grow greatly in 2024!

Following the basic course, I took all of the intermediate course 1 lectures. The process of finding the principles was fun, and it was a lecture that helped me fill in the depth of Java that I lacked. [Reason to learn] This lecture also clearly explained the part about 'Why should I learn this?'. In preparation for the upcoming advanced course, I was impressed by the way the difficulty of the concepts was differentiated and the part that I needed to know now was explained in depth and the preparation for the next lecture was also done. In addition to the basic course that explained the parts that everyone had heard of but did not understand properly, it was a time to scratch the itch by covering concepts that I had heard of a lot but did not know properly. [More solid examples] In addition to the smooth lectures in the basic course, I was impressed by the solid examples, and the examples made me think that the depth of my thoughts increased as the difficulty level increased. In terms of the CSAT, it felt like looking at the evaluation center's problems rather than the mock exams on the market. [Highly recommended for those in the field] Many people in the field are developing with Java, but there may not be many who know it as deeply as you think. I also work with Spring Framework and Java, but I don't think I can confidently say that I know Java. I am sure that this lecture will be a time for those in the field to understand and utilize concepts that they did not know or could not confidently talk about. [Viewing the lecture more valuable] I think it was really hard to find any regrets this time. Since it is an 'online lecture', everything can be resolved. If it is difficult to keep up with Younghan's respectful typing speed, you can watch it at a slower speed or watch it again. I think the difficulty level has increased compared to the basic version, so a lot of review and understanding time is needed. In order for this lecture to be more valuable to us, I think a lot of review and understanding and thinking time is needed. Watching the next lecture is important, but it would be better to first try to understand it perfectly! [To Younghan] In the last lecture, I urged you to do the guitar. You said that your child will be born in May...and asked for a quick release.. Your child came two weeks early before you finished listening to the first part of Intermediate. The words, 'new but always together' really hit home. I'm so curious about how Younghan spent his personal time after becoming a father! I'm definitely short on time, but I'll try to follow along slowly and steadily.
Congratulations to suco :) Usually, when you become a father, you start to think that you have to work harder for your family. But I think balance is important. For example, I think it's good to spend time at home or on weekends with your family and for your wife who is having a hard time. And making good memories with your child is also very precious. Instead, I think it's wise to think about ways to make time by going to work a little earlier on weekdays, studying separately during lunch, or using your commuting time to make up for the reduced time :)
