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 "Eureka!" moment!
A lecture filled with the know-how of a mentor and star instructor with 25 years of experience!
Java is a language that every developer must know, and you can master it from the basics all the way to the end. From fundamentals for beginners to realistic and specific examples of how each object-oriented programming technique is used, we will resolve your questions and difficulties.

It has been four and a half years since I wrote the Java book. Since then, over 30,000 copies have been sold, and the number of students taking my courses has grown significantly. The free Java lectures I released alongside the book have also aged over that time. Since then, various contents and examples have been updated through numerous other lectures. I am delighted to open this renewed version on Inflearn.
The process of learning something new, not just programming, is a difficult task for anyone in any field. Only those who endure and enjoy that time can become experts. I believe programming is similar to studying mathematics. To be good at math, you need to practice a lot, right? Programming is the same. You need to be able to logically interpret and translate problems into programs when faced with many exercises, and it requires a lot of practice and time until you acquire such skills. Teacher Eun-jong will be with you through that time.
In this course, we will do all the coding together. As you follow along with each lecture, you will soon find yourself becoming familiar with coding and programming. Teacher Eunjong will be with you through your "time of garlic and mugwort."

I am a non-major, but 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've learned Java, but I don't have a sense of how it's actually used.
I learned object-oriented programming, but I don't know how to apply it.

I'm taking a government-funded course, but my true teacher is right here. I want to take the salary from that instructor and give it to you. Calming my anger from the government course by listening to Silver Bell... Silver bell, silver bell, silver all the way...

I first encountered Java through a government-funded training program, but I honestly want to give the money I spent on that course to the instructor of this free lecture. Both the voice and the teaching are excellent. It's even better because I can adjust the speed as I like, unlike the government program. Inflearn is the best... Teacher Eun-jong is the best...

★★★★★
The instructor's incredible diction makes it easy to understand even at 2x speed, the explanation style is so clear that it's impossible not to understand, and the video lengths are appropriate. It covers deep topics that other light courses might skip, yet maintains a clean and logical flow by providing key terms. This is truly legendary.

Q. I have never studied programming before; will I be able to understand the course if I take it?
You can start. This course is designed for beginners. You just need to study step-by-step, starting from the basics of programming. However, starting any new field is difficult and challenging. In particular, to become good at programming, you must invest a significant amount of time and effort ^^
Q. Is learning the Java language advantageous for becoming a developer?
I think choosing which field of development you want to enter should come first. The importance of each language varies depending on the job. Currently, Java developers work in areas such as web and Android app development. If you want to develop in fields like networking or games, it is more appropriate to study C or C++.
Q. Is the course content significantly different from the book (Do it! Java Programming for Beginners)?
Basically, since I created both the book and the lecture, there are many similarities. However, there is content that couldn't be fully included in the book, and examples with large volumes that were omitted due to space constraints are provided in the lecture.
Q. What is the reason for dividing the lecture into Part 1 and Part 2?
For those who are beginners, it would be best to study Part 1 first. Once you finish Part 1, you can learn about various Java classes, data structures, and algorithms in Part 2. We have separated the parts so that those who already have introductory knowledge can take each course individually to gain broader and more diverse knowledge through Part 2.
You will learn various elements necessary for practical Java application, such as utilizing various JDK classes, implementing data structures, solving algorithm problems, Java I/O, and socket programming.
Who is this course right for?
Those who want to get started with programming
Those who are learning Java programming for the first time
Those who have already practiced object-oriented programming in other languages but wish to learn it through 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!!!
