Just knowing Java grammar? That won't do!

Why Kim Young-han created Java lectures

•••

“I wanted to create a proper Java course that would create proper developers needed for real work.”

Now, why Java?

Many companies, including big tech companies, unicorn startups, and others, use Java to build backend systems.

Anyone who is just starting out in programming has probably thought about this at least once.
'There are many other programming languages, so why should I learn Java?'

The reason is clear. Java has many advantages, but it is especially a widely used language in practice.

There are many different areas that developers are responsible for.

  • Front-end development that is responsible for the operation of the web browser screen.

  • Backend development, which is responsible for the server logic that interacts with the database.

  • Developing mobile apps that run on mobile devices (iOS/Android)

  • Numerous other fields


Practical needs in software development: 10% mobile app development, 20% front-end development, 70% back-end app development

The most in-demand field among these right now is by far backend developer .
Moreover, most of the backend systems of major domestic companies, including Naver and Kakao, are developed based on Java.

If you want to be more open to opportunities, Java is the 'most likely' choice.

Even if you don't get a job right away or go to a good company, if you steadily build your skills in Java, your chances of getting into a major company will be much higher than if you use other languages.

I hope that those who are new to programming will get off to a good start through this introductory Java course.

Kim Young-han's Practical Java Roadmap

This lecture is the first lecture of Kim Young-han's Practical Java Roadmap and is intended for those who are new to programming.

Kim Young-han's Practical Java Roadmap

The lecture "Kim Young-han's Introduction to Java"

Anyone who wants to learn Java language

I studied Java, but
For those who want to build a solid foundation

Developer job seeker

We thoroughly lay the foundation for the fundamentals.

Variables, operators, conditional statements, loops, arrays, functions (methods)...
Although they are the most basic grammar, did you know that they account for 80% of coding ? That is why it is so important to properly build a foundation in programming.

In this course, we will learn the most basic parts of all programming languages. The goal is to go beyond simply knowing the grammar and gain a solid foundation that can be applied in practice.

Special features of this course

1) Our goal is none other than practice.

  • We cover the basics that are frequently used in practice in depth and with certainty.

  • We boldly exclude features that are not used in practice.

Even if you invest the same amount of time, some people will do well and others will do poorly. Where does this difference come from? Java is too broad and there are many functions to study. That's why many beginners lose their way and wander around.

If there are 100 Java features, you don't need to learn all 100 of them. Learning unimportant features that you don't use in practice is a waste of time. You shouldn't spend a lot of time learning features that you don't use.

Learn practical, feature-oriented Java programming

This course will save you time so you can move on to the next step quickly.

2) Follow the code and understand naturally.

  • We provide numerous examples to help you understand the concepts naturally through code.

Think back to when you learned to swim. Programming is actually something you learn more by following along with actual code than by understanding it in your head.

Rather than studying theories separately outside the water, I have organized the lecture so that you can learn Java as if you were swimming in the water with me. Even when explaining theories, example codes are provided so that you can fully understand the theory. Try to naturally understand the basics while following the code.

Understanding Java Programming with Code

3) We show you the problem and solution together.

  • You can develop the ability to solve problems with code.

All programming is like solving a problem directly with code. If you learned how to swim, you have to practice what you learned in the water to make it your own.

This lecture emphasizes the process of learning by solving problems. This is because in order to learn properly, you need to be able to solve problems based on what you have studied. In addition, I will show you the process of solving problems with you through the class. There will be things you will naturally learn by watching a developer with a long experience in the field solve problems.

Java Programming Example Problems and Solutions

“Rather than thinking about what more I should teach, I thought more deeply about what absolutely must be known.”

In this 'Kim Young-han's Practical Java Roadmap', my goal is to create capable developers who have solid fundamentals necessary for real work. I hope that this lecture will be a good starting point for those who want to learn Java properly, and I will help you become a good developer.
