[Do it Java Programming Introduction with Teacher Eunjong] is back with a renewal!

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.

Introduction to Java Programming,
With Teacher Eun Jong! 🧙

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 . Teacher Eunjong will be with you during that time.

This lecture 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 for your "Garlic and Mugwort Time."


I recommend this to these people 🙋

I learned Java, but I have no idea how it is actually used.

I don't know how to utilize the various classes in Java.

There are many unfamiliar and difficult parts, such as lambda expressions, streams, and generics.

I want to try a real project with Java.

★★★★★

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...

-nose***

★★★★★

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


- not***

★★★★★

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 better because I can freely control the time by speed. Inflearn is the best.. Eunjong teacher is the best..

-seed***

★★★★★

The instructor's incredible diction that sticks in your ears even when you listen at 2x speed, the explanation style that makes no sense if you don't understand it after listening to it , the appropriate length of the video. There are deep contents that other light lectures don't cover, but the flow is clean by only providing keywords. It's a real 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 .

-Wo***

★★★★★

I think this is the best course for beginners and existing developers to learn the basics of Java . I would 100% recommend this course to my juniors and colleagues!

Expected Questions Q&A 💬

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.
