I had an eye disorder and was disabled, but I started Java again to pursue my dream. It has the basics and examples properly, so it would be good for beginners. It is also good for majors like me. I recommend it as a Java course.

(Advantages) 1. Even non-majors can learn Java in a short period of time 2. Interfaces, lambda expressions, and streams are explained very easily. (Disadvantages) 1. Since the lecture time is short, I have to find a separate book to study detailed contents such as classes, inheritance, polymorphism, and interfaces. --> Honestly, I think it is natural because the lecture time is short. --> It would be perfect if it was supplemented with detailed contents in a PDF file, but the cost is too cheap, so I think it is too unscrupulous. (Conclusion) I have listened to the basics, so I would appreciate it if you could give me an advanced version.

Hello, Nadocoding. I got to know you through your Python lectures on YouTube. Learning Python was really fun. The concept of concretizing and realizing what was in my head through a program was really fun. Actually, I worked in distribution and loading and unloading couriers for several years, and then I first encountered the language called Python.... But I decided to quit my job a year after I encountered the language... I'm 30 years old, but I was so amazed that this field was so interesting and that the concept of studying fit me so well. I'm taking Java lectures in advance before entering a government-funded academy, but as expected, you're training me with a more solid curriculum than when I was learning Python :) It's scary to start at such a late age, but I think I'll be able to accept any situation and any appearance if I jump in and break and shatter rather than regret not doing it. I talked a lot because the future was dark... ㅋㅋㅋ Nadocoding, you're really helping me a lot. Thank you so much.

"It's so much fun.
The joy of applying each short topic you teach is insane. The way the lectures are arranged—addressing the parts where I get stuck or curious right after I try applying them—seems to amplify the fun of learning.
I'm actually sad that I have to go to sleep."

*The reviews below are from the YouTube channel lectures operated by Nadocoding.
This is a brilliant lecture!! You've organized it well step-by-step, considering the perspective of a beginner learner.
The content is optimized, but the instructor's delivery is the best.
Thank you. Thanks to you, programming, which I had been hesitating to start for a long time, has finally become clear in my head. I feel like my world has expanded significantly. I am currently working on a project to maximize the efficiency of audiobook production using AI, and I think I will be able to succeed :-) Thank you!
I'm leaving a comment because I'm truly so grateful. I've taken several paid and free courses, but I gave up on all of them. I urgently needed a basic Python lecture because I have to study machine learning, and I've ended up finishing almost the entire basic course by Nadocoding. It's truly a whole new world. It's much better than expensive paid lectures. I also love how you pull examples from real-life situations haha. I'll be looking forward to your future content on data analysis and machine learning! Thank you so, so much!
I really didn't know where to start and had given up, but this lecture sticks in my head so well that I can speak it and write it down after just one watch..! Thank you, teacher. This is truly a national treasure-level lecture 😭
It says it was 10 months ago that I first started programming with this video. Now, I've been working as a Java developer at a pretty decent solution company for about a month. I started my studies with half-doubt, but thanks to this video, I was able to quickly and easily develop an interest in programming . Thank you so much for making such a great video, and I hope everyone studying with this video achieves their own goals!
Without a doubt, this has become a life-changing lecture. I, who didn't even know what code, data types, or lists were, reached a level where I could pass the pre-test for a government-funded data course with just this one video. Even now, while taking the course, there isn't a day that goes by where I'm not grateful, wondering how I would have been able to write code in Python if I hadn't taken this lecture! Beginners, don't be afraid; if you listen diligently for a week, you too can become proficient in Python.
I'm a baby coder attending 42 in Paris... You explained everything I've been curious about since Piscine so detailedly and kindly that I understood everything T_T I've never coded before... I didn't understand what my friends were saying even when they explained it to me, but I'm leaving now having understood every single thing T_T Thank you so much T_T I'll visit often!
This person's lectures are truly at the level of a talent donation... Explaining stiff topics very smoothly... A teaching genius...
"I really enjoyed this lecture as well. It made me want to try fetching stock information I'm interested in and even processing it graphically.
Thinking about why people who watched this lecture praise it so highly, I believe it's because while most books, lectures, and seminars only teach successful results, this lecture gives the feeling of growing together through raw mistakes. It provides the confidence that "I can do it" and uses an apprenticeship-style approach by suggesting what to try on your own to gain deeper knowledge. It is a great lecture that makes me think about many things beyond just the course content.^^"
These days, I'm spending all my time watching and following Nadocoding's lectures haha. I can't believe this is already the last of the Python lectures!!! I'm really looking forward to the next ones too haha. Usually, you're supposed to feel good as you run out of remaining lectures, but the lectures are so, so good that I'm actually sad they're ending 😊 I'll wrap up this episode well too! Thank you for the great lectures always !!!!!!!!! Fighting ୧ʕ•̀ᴥ•́ʔ୨
Hello. The long lecture, which spans over 9 hours, was great because it wasn't boring at all and it was fun to learn things bit by bit. It was a meaningful time as I could think of ideas to apply to my actual work while using various modules and functions. I look forward to the next lecture. Thank you so much.
I was working in a non-technical field for my entire career until the age of 30, when I happened to start with Python basics and made it all the way here. Thanks to your dedicated teaching, I was able to transfer from the HR team to the development team and am living happily now. I feel sorry that I cannot meet you in person to say hello, but I am so grateful. Thank you for guiding me on my life's path.
Who is this course right for?
Those who are learning coding for the first time
Computer science (or related field) major (including prospective students)
Those who wish to find employment as a developer
Those who desperately want to learn Java the easy way
Need to know before starting?
It's okay even if you don't know anything!

Full-time Nado Coding's Java course It was a lecture with a clean progression, appropriate lecture length, and a powerful voice. The explanations after the class part were surprisingly easy to understand. I can see traces of a lot of preparation. I received a lot of help from the Python lecture, and now Java is also helping me like this. I will work even harder. Thank you, instructor. Thank you for your hard work.
Hello, bigcat0815 You completed the long lecture really quickly 🎉 I thought a lot about making easy examples and code structures because the class might be difficult for beginners, but I'm so happy that you said it was easy to understand 😭 Thank you so much for your valuable review 🙏 I hope the content you learned this time will be helpful for places where Java is needed. Have a warm year-end and a happy new year! Thank you 😊 - I also code

Hello. I am a late bloomer who applied for a boot camp and then dropped out and is studying on my own!! First of all, if you are a non-major like me and are learning Java for the first time, you may think that the lecture content is somewhat lacking. In my case, I read 'Java Essentials' once and took this lecture. I think I understood and learned more than 90% easily. Of course, it is also thanks to Nako-nim's powerful teaching skills!! Must-reads -> Nako Java (dessert after the main dish) Nako Java -> Must-reads (main dish after the appetizer) I think you can choose according to your taste!! Thank you, Coding-nim : )
Hello, Yuntoben! It is not easy to study a programming language on your own without anyone's help as a non-major. In particular, it requires a lot of will and effort to read a thick book like 'Java's Essentials' instead of an online lecture. 👏 I think Yuntoben already has enough perseverance and concentration since you read it once. Compared to a book that is almost 1,000 pages long📚, 20 hours of basic lectures👨🏫 may feel a little lacking. Since it is a basic course, I boldly excluded parts that suddenly increase in difficulty or that beginners do not need to know. I think it is more important to learn the overall content and complete it from the beginning to the end at least once rather than studying every topic in detail and giving up in the middle. That way 💪 you can gain confidence and get a feel for what programming is like 😁 I think it's a really good study method to study like you're studying now, whether you first read the book and then review the lecture, or study the content through the lecture and then reinforce it with the book. Your analogy is good 😲 I sincerely thank you for taking the class, and I sincerely hope that you will master Java through this opportunity and get a job where you want 🙌 Thank you. - I also code
