I am a non-major who wants to get a job in the developer field. I only did front-end, but I thought I would have to do back-end to survive in the market, so I started studying back-end as well. Seriously.. Teacher Yeong-han is G.O.A.T. I took a Java programming class at school, and although it was a major class, it started from the basics, but I got a C+. ㅋㅋㅋㅋㅋ Of course, I didn't study like crazy, but I used Eclipse, a development environment with poor readability, and since it was an English A class, the professor's communication skills weren't good. That's why I gave up Java. But since I thought I had to do back-end, I thought I had to do Java, so I started taking Teacher Yeong-han's class.. Seriously.. I'm just crazy because he explains things so easily. Don't worry about other Java classes. Take Teacher Yeong-han's class, really. I started with the basics, but after listening to this class, I gained confidence, so I signed up for other Java classes. I really want to quickly get into tech and write a good resume so I can get a job! Class tips! Please try to do it all by hand and solve the problems first and then listen to the lecture. I had a lot of experience in school classes... So I didn't listen to the lecture for the basic problem solving and just solved them on my own, checked the answers, and moved on, and I learned faster. I hope you all get the results you want!!~
