I was worried and started out as a beginner. When I first listened to the first 10 lectures, I didn't understand anything, but as I listened to it repeatedly, I gradually understood more and more, and I began to understand what the instructor was saying. Other lectures are good, but Eun Jong-seon's lectures are really pleasing to the eyes and ears. I think I made a good decision to sign up for the class. For those who are just starting out and trying it for the first time like me, I recommend that you don't worry and try it from the beginning because you won't understand. I think it's best to listen to all the classes repeatedly.

When studying Java, the object-oriented part was always difficult to understand and I got stuck, but thanks to the intuitive examples and materials that helped with understanding, I was able to get a solid feel for it with this lecture :) It quickly summarizes the core contents about control and explains the contents about object orientation along with frequently used patterns, so I was able to study while thinking about what kind of code to use in what situation. I want to study Part 2 that will be released soon. I recommend it as an introductory Java lecture!

It's really good for taking baby steps before studying in earnest. It explains concepts and terms in an easy-to-understand way, and if this lecture is difficult or you don't understand it, it's just because you have low comprehension skills.

A Java lecture that even non-majors and liberal arts students can understand with a 'slap!'
A lecture full of the know-how of a renowned lecturer and mentor with 25 years of experience!
Java language, which is a must-know for developers, can be mastered from the very beginning. From the basics for beginners to how each technology of object-oriented programming is used, we will solve your questions and difficulties with realistic and specific examples.

It has been four and a half years since I wrote the Java book. During that time, over 30,000 copies of the book have been sold and the number of students taking the course has increased significantly. The Java lectures that were released for free along with the book have also passed a similar amount of time. Since then, various contents and examples have been updated as I have given various lectures. I am happy to have renewed and opened it on Inflearn.
Not only programming, but the process of learning something new is difficult for anyone in any field. Only those who overcome that time and enjoy it can become experts. I think programming is similar to studying math. To be good at math, you have to practice a lot, right? The same goes for programming. When you encounter many practice problems , you need to be able to logically interpret them and transfer them to programs, and until you have that ability, you need a lot of practice and time . Eunjong will be with you during that time.
This course covers all the coding together. If you follow each lecture, you will find yourself becoming familiar with coding and programming. Eun Jong-sam will be with you during your “Garlic and Mugwort Time.”
I recommend this to these people 🙋
Even though I'm not a major, I want to learn coding and become a developer.
The terminology is so difficult that it's not easy to get started with programming.
I learned Java, but I have no idea how it is actually used.
I learned object-oriented programming, but I don't know what to do with it.
What you have learned will be made yours through practical examples .
Provides 'review' questions to check what you have learned
Natural acquisition while following the code
Basic knowledge of programming languages learned through Java
Installation and example practice provided for both Windows and Mac
Provides how to download Github code (provided in additional video)
This introductory lecture is divided into Part 1 and Part 2.
In this lecture, Part 1, you will learn the basics and core of object-oriented programming, and in Part 2, which will be opened later, you will acquire skills that can be used in practice through various Java classes.
Here's what you'll learn in Part 1:

I'm listening to the national scholarship, and my teacher is here. I want to take the salary from that instructor and give it to the teacher. I'm listening to the national scholarship, and I'm angry, so I'm listening to Silver Bell to calm down... Silver Bell, Silver Bell, Silver All the Way...

This is the best lecture among Java lectures, explaining everything in detail step by step from the basics. Everyone, listen to this lecture for Java!

I first encountered Java through government-funded education, and I would like to give the money I spent on that lecture to this free lecture instructor, really. The voice and the lecture are both great. Compared to government-funded education, I like it even more because I can freely control the time by speed. Inflearn is the best.. Eunjong teacher is the best..

The instructor's incredible diction that sticks in your ears even when you listen at 2x speed, the way he explains things that you won't understand if you listen to it , and the appropriate length of the video. There are deep contents that you wouldn't find in other light lectures, but the flow is clean and flows by only providing keywords. He's a true legend.

I have taken many Java lectures, but compared to the famous lecturers who are known to be long and sluggish, this one was more friendly and detailed, and I liked the part where it explained why it is used and how it is used .

Q. I have never studied programming before. Will I still be able to understand the course?
You can start. This course is for beginners. You can study programming basics step by step. However, it is difficult and hard for anyone to start from scratch. In particular, to become good at programming, you absolutely have to invest time and effort^^
Q. Is learning the Java language beneficial to becoming a developer?
I think it's best to first choose which field you want to be a developer in. Each language has a different weight in the work. Currently, Java developers are working on development for web, Android apps, etc. If you want to develop in the network or game field, it's right to study C or C++.
Q. Is the course content very different from the book (Do it Introduction to Java Programming)?
Basically, there are many parts that are the same as the book and lecture that I wrote. However, there are some contents that could not be included in the book, and there are many examples that could not be included in the book due to space constraints, so they are provided in the lecture.
Q. Why was the lecture divided into Part 1 and Part 2?
For those who are just starting out, it would be a good idea to start with Part 1. After completing Part 1, you can learn various classes, data structures, and algorithms in Java in Part 2. For those who already have the knowledge of Beginner, we have separated the parts so that you can take Part 2 separately to gain broader and more diverse knowledge.
You will learn about various elements necessary for actually using Java, such as utilizing various classes in JDK, implementing data structures, solving algorithmic problems, Java input/output, and socket programming.
Who is this course right for?
Those who want to get started with programming
If you are new to Java programming
If you have already done object-oriented programming in another language but want to learn it in Java

I majored in Computer Science at Dongguk University and received a Master's degree in Computer Science from the Seoul National University Graduate School. During my professional career, I carried out numerous development projects using languages such as Java, C, and C++. I have also taught courses in Java, Web, Data Structures and Algorithms, Mobile, and Design Patterns at Bit Computer and T Academy.
I have taught programming to non-majors at Kookmin University and Kyung Hee University, and served as an adjunct professor at NHN NEXT, teaching Java programming and programming practice. Having worked as a developer for 10 years, I have a deep understanding of what is required in the field, and through another 10 years of teaching, I have come to truly understand the perspective of beginners.
My primary interest these days is helping people from all walks of life—from elementary students to adults—gain an interest in and study the wonderful world of programming. Currently, I serve as a mentor at Innovation Academy (42 SEOUL).

I'm glad that you, a beginner, got help. It may be hard to understand after hearing it once... But I hope you listen to it repeatedly and code along with it. The keyboard is different when you code than when you write a document. You need to get used to the keyboard in your hands to gain confidence. Fighting!!!
