"It's so much fun.
It was crazy fun to apply each short topic that was taught. I think the way the lectures are arranged so that if you get stuck and have questions while applying, they answer them right after, amplifies the fun of learning.

👏 The new lecture of Nado Coding that many students have been enthusiastic about, Java Basics, has finally been completed ✨
Java is a language that has been loved for a long time. It is used in various fields such as web, mobile, and desktop application development, as well as automation, machine learning, and data analysis. If you are considering a job in the IT industry, you can never give it up.
🎲
With a systematic curriculum
Let's start from the basics step by step.
💻
Provides quality source code!
Later on, you can just look at this.
⏰
About 10 minutes long in the lecture hall
Study anytime, anywhere.
🛫
Easy to understand even for non-majors
Let's use familiar examples from around us.
🔑
Through a quiz at each chapter
Develop problem-solving skills
📢 Please check before taking the class!
Only the essentials you need to know! Stop wasting time. No more small talk, learn quickly and efficiently .
※ Caution: No matter how fun it is, you must sleep 😅
The more difficult the content, the easier and more fun it is to learn. Don't study forcibly in boring classes and rubbing your sleepy eyes. It is explained really easily with examples that anyone can be familiar with . Thanks to this, many people who had given up have tried coding again.
We provide a quiz that allows you to check what you have learned. Through feedback over the years, we have become convinced of the value of the experience of writing code yourself. Through quizzes on various topics , your skills and confidence will increase 😎
💬 Images are illustrations related to examples or quizzes used in each chapter🖐

*The review below is a review left for a lecture on the YouTube channel operated by Nadocoding.
This is a great lecture!! It is organized step by step well considering the beginner's perspective.
Not only is the content optimized, but the instructor's delivery skills are top-notch .
Thank you. Thanks to you, the programming that I had been wandering around for a long time has been completely organized in my head. I feel like the world has become bigger . I am working on a project to make audiobook production extremely efficient with AI, and I think it will be successful :-) Thank you!
I'm leaving a comment because I'm so grateful. I've tried many free and paid courses, but I gave up on them all. I need to study machine learning, so I urgently needed a basic Python course. I'm almost done with the basic Nado Coding course. It's really a new world. It's much better than expensive paid courses. I also really like how you use real-life examples.😊😊 I look forward to data analysis and machine learning in the future! Thank you so much!
I really didn't know how to do it, so I just let it go, but after watching this lecture, it's so well-received in my head that I can say it out loud and write it down with my hands..! Thank you, teacher. This is truly a national treasure lecture 😭
It says that I started programming 10 months ago with this video. I have been working as a Java developer at a pretty good solution company for about a month now. I started studying with half-heartedness, but thanks to this video, I was able to learn programming really quickly and easily. I was able to catch your interest . Thank you so much for making such a great video. I hope that everyone who studies while watching this video will achieve their goals!
I can confidently say that this lecture changed my life . I didn't know what code was, what data types were, or what lists were. But with just this video, I was able to pass the pre-exam for the national data course. And I'm grateful for more than a day or two of thinking about how I could have written code in Python if I hadn't taken this lecture while taking the current course! Beginners, don't be afraid. If you listen diligently for a week, you too can become a Python user.
I'm a 42 year old babycoder from Paris.. All the things I was curious about since I fled were explained in detail and kindly, so I understood everything 😢😢 I've never coded before.. Even when my friends explained it to me, I didn't know what they were talking about, but now I understand everything 😭😭 Thank you so much 😭😭 I'll come often!
This person's lectures are truly a donation of talent. He explains difficult things very smoothly . He is a genius at teaching.
"I also enjoyed this lecture. I now want to try getting stock information that interests me and processing it into graphics.
When I think about why people who have taken this course rave about it , I think that most of the books and lecture seminars we learn from only teach us successful results, but this course teaches in a way that gives us the feeling of growing together while making mistakes, the confidence that we can do it, and additionally, asking us to try something on our own to learn more deeply. It is a great course that makes us think about many things in many ways, not just the content of the course^^"
These days, I've been watching and following Nadocoding's lectures all day and time is flying by 😊😊 This is already the last lecture on Python!!! I can't wait for the next ones 😊😊 Originally, I should be happy when there are no more lectures left, but the lectures are so good that I'm sad 😊 I'll finish this episode well too! Thank you always for the great lectures!!!!!!!!! Fighting ୧ʕ•̀ᴥ•́ʔ୨
Hello. It was a long lecture of over 9 hours , but it was not boring at all, and it was fun to learn little by little . It was a meaningful time because I was able to use various modules and functions and think of ideas that can be applied to real work. I look forward to the next lecture. Thank you very much.
At the age of 30, I have been working as a freelancer all my life, and by chance, I have come this far from the basics of Python. Thanks to your diligent teaching, I have been transferred from the HR team to the development team and am living happily . I would like to meet you and say hello, but I am sorry that I cannot, and I am so grateful. Thank you for guiding my life.
Who is this course right for?

(장점) 1. 빠른 시간 내에 비전공자라도 자바에 대해 익힐 수 있음 2. 인터페이스, 람다식 & 스트림 부분을 굉장히 쉽게 설명해주십니다. (단점) 1. 강의 시간이 적다 보니 클래스, 상속, 다형성, 인터페이스 등 세부적인 내용은 따로 책을 찾아서 공부해야 함. --> 솔직히 강의 시간이 적다보니 당연한 부분이라고 생각합니다. --> PDF 파일로 세부적인 내용에 대해서 보충하는 식으로 하면 완벽할 것 같습니다만 비용이 너무 저렴하여 이건 제가 너무 양심이 없는 것 같네요. (결론) 기본편 다 들었으니 심화편 내주시면 감사하겠읍니다.

나도코딩님, 안녕하세요. 전 유튜브의 파이썬 강의를 통해서 나도코딩님을 알게되었습니다. 파이썬을 배울땐 정말 재미있더군요. 제 머릿속에 있는것을 프로그램을 통해서 구체화하고 실현화 한다는 개념이 너무 재밌었습니다. 실은 저는 몇년동안 유통업, 택배 상하차만 하다가 처음으로 파이썬이라는 언어를 접하게 되었거든요.... 그런데 언어를 접한 이후 1년 되던날 사직을 결심하게 되었습니다... 나이가 30이지만 이 분야가 정말 재미있고 공부한다는 개념이 이렇게 저랑 맞을수있다는게 너무 신기 했어요. 이제 국비지원학원에 들어가기에 앞서 자바 강의를 미리 듣고 있지만 역시나 파이썬때보다 더욱 탄탄한 커리큘럼으로 저를 단련시켜 주시네요 :) 늦은 나이에 이렇게 시작한다는게 한편으로는 두렵기도 하다만 그래도 하지않고 후회하는것보단 뛰어들고 깨지고 부서진 후에 제 모습을 본다면 어떤 모습이든 어떤 상황이든 떳떳하게 받아드릴수 있을것 같네요. 앞이 컴컴한 상황이라 말이 길었네요... ㅋㅋㅋ 나도코딩님, 큰 도움이 많이 되고 있습니다. 정말 감사드립니다.

풀타임 나도코딩님의 자바 강좌 깔끔한 진행과 적당한 강의 길이, 전달력있는 목소리 어디 하나 빠질것이 없는 강의 였습니다. 클래스 파트 이후의 설명은 놀라울 정도로 이해하기 쉽게 진행해 줍니다. 많은 준비를 한 흔적들이 보입니다. 파이썬강의도 도움 많이 받았는데 자바도 이렇게 도움을 받게 되었네요 더욱 열심히 노력하겠습니다. 강사님 고생많으셨습니다. 감사합니다.
안녕하세요, bigcat0815 님 긴 시간의 강의를 정말 빠르게 완강하셨네요 🎉 클래스부터는 입문자분들에게 어렵게 느껴질수 있어서 쉬운 예제와 코드 구성을 정말 오랫동안 고민하고 만들었는데, 이해가 쉬웠다고 해주시니 너무 뿌듯합니다 😭 소중한 후기 진심으로 감사드리구요 🙏 자바가 필요한 곳에 이번에 학습하신 내용이 도움이 되시길 바라겠습니다. 따뜻한 연말 보내시고, 다가오는 새해 복 많이 받으세요! 감사합니다 😊 - 나도코딩 드림

안녕하세요. 저는 비전공자 출신에 부트캠프를 지원했다 하차하고 독학하고 있는 늦깎이 학생입니다!! 우선, 저 같은 비전공자면서 자바를 처음 공부하는 것이라면 다소 강의 내용이 부족하다고 생각 할 수도 있을 거 같습니다. 저의 경우 '자바의 정석'을 1회독 하고 이 강의를 수강하게 되었는데요. 90% 이상 수월하게 이해하고 배웠던 거 같습니다. 물론 나코님의 막강한 강의력 덕분이기도 하지만요!! 필독서 -> 나코 자바 (메인 요리 후 먹는 디저트) 나코 자바 -> 필독서 (에피타이저 후 먹는 메인 요리) 입맛에 맞게 골라 드시면 될 거 같습니다!! 감사합니다 나도 코딩님 : )
안녕하세요, 윤토벤 님! 비전공이신데 누구의 도움 없이 독학으로 프로그래밍 언어를 공부한다는 것은 정말 쉽지 않은 일입니다. 특히 온라인 강의가 아닌 '자바의 정석'과 같은 두꺼운 책을 본다는 것은 굉장한 의지와 노력이 필요하죠. 👏 1회독을 하셨다는 부분에서 윤토벤 님은 이미 충분한 끈기와 집중력을 갖고 계신 분이리라 생각됩니다. 거의 1,000 페이지에 달하는 책📚 에 비해서 20시간의 기본편 강의👨🏫 는 어쩌면 조금 부족하게 느껴질 수도 있을 것 같아요. 기본편이기에 사실 난이도가 갑자기 높아진다거나 굳이 초보자 입장에서는 몰라도 되는 부분은 과감하게 제외를 하기도 하였습니다. 저는 모든 주제에 대해 세세하게 뜯어서 공부하다가 중간에 포기하는 것보다는, 전반적인 내용을 익히면서 처음부터 끝까지 한 번이라도 완주하는 게 더 중요하다고 생각해요. 그래야 💪 자신감이 붙고 프로그래밍이 어떤 것인지 감을 잡을 수 있거든요 😁 지금 공부하시는 것처럼 책을 먼저 보고 강의를 복습 삼아 보시거나, 강의로 먼저 내용을 공부하고 책으로 다지거나 모두 정말 좋은 학습법이라고 생각합니다. 비유가 좋으시네요 😲 수강해주셔서 진심으로 감사드리며 이번 기회에 자바를 마스터 하셔서 꼭 원하는 곳에 취직하시기를 진심으로 바라겠습니다 🙌 감사합니다. - 나도코딩 드림
