For everyone who wants to study Java introductory, I highly recommend Hongpak's lectures. They are so fun and easy to understand!!!!! + Thanks to Hongpak, the concepts I vaguely knew were now clearly understood, and the concepts I didn't know were completely organized! Other Java concept lectures were boring and there were parts I didn't understand, so it was really hard to listen, but Hongpak's lectures were so fun that I didn't realize how much time had passed. I really wish Hongpak would cover concepts like lambda expressions and threads more. Please..

I feel so fortunate to have found such a great lecture even now. This is a lecture that I am truly so grateful for. I think that the 19,800 won is definitely worth it. I recommend this lecture to the following people: 1. People who have seen the concept roughly but still can't get the hang of it 2. People who want to understand the concept of object orientation 3. Complete beginners who don't know anything but still want to learn I divided it into 3 categories above, but I think it's a good lecture for anyone. I'm really grateful for the great lecture again, and I'll finish the lecture and leave another review as a completion review~

I'm not in a position to judge anyone, but... from the perspective of a student, I thought it was really fun and well-organized. If there's one thing I regret... the lecture is over. ㅠ Please upload a new lecture soon. I'm learning well and going. It's really the best.

Who is this course right for?

  • Object-oriented programming. It's hard to explain, isn't it?

  • I want to follow along well with the government-funded education!

  • Class? Object? Aren't they both the same?

  • I understand the concept, but what about actually writing code?

  • Object-oriented code! For those of you who want to make it well!

Need to know before starting?

  • Java introductory knowledge (variables, methods, conditional statements, loops, arrays)
