I also completed the intermediate 1st part:) In fact, I am taking the Java lecture while preparing for employment, so I thought that it was necessary to build up the basics, but honestly, I was anxious. I studied Java and thought when I would learn Spring, but in the last lecture, Spring was also made in Java, and Younghan said that if you have a solid foundation in Java, you can learn Spring quickly, which comforted me... Thank you~ The intermediate part is definitely more difficult. I really need to review...! Is it effective to look at the textbook, follow the example code, understand it, and try solving the problems again? Also, even if I am in a hurry, would it be better to go to the intermediate 2nd part after reviewing...? I have a question....!! Thank you for the great lecture that tries to teach the essence~~~ I will cheer you on and fight for the remaining lectures~~~!!!
