I am a junior Java developer entering my first year. I studied Java, but I always felt that I lacked concepts in real life. Through this lecture, I am gaining x1000 times more confidence as I can imagine the concepts that were vague until now. That is why I am enjoying development these days, and I hope the intermediate-advanced version comes out soon.~~ Thank you so much~ for giving me a ray of light~ Additional) Complete~~ A lecture that anyone preparing for Java must study repeatedly!!!
