Thunderbolt Java-[Basic Beginner's Edition]

[ Learn Java at lightning speed! Thunderbolt Java - [Introduction to Java for Beginners] ]

Anyone who's ever stuffed their head with too much boring knowledge knows that it's all useless.

Isn't it good to know more? It's definitely helpful for the information processing engineer/industrial engineer certification exams. Of course, it only applies to the written exam.

I don't have any experience, so how can I take the practical exam? I don't think I can make any programs anyway.

So, I prepared it!! A Java basics course that will help you quickly learn only the essentials among the essentials.

Rather than someone who knows a ton of stuff but can't build anything properly, it's more important to be a technician who can actually create programs even if they know a little less . Programming isn't something you learn to become a scholar. It's something you learn to become a technician.

Learning quickly means, strictly speaking, picking out only the core of the core, and it goes without saying that the criteria for picking out those core elements are absolutely important.

So, what is the standard for extracting only the essentials from the vast field of programming?

Where does that standard come from? Of course. It comes from countless experiences and decades of accumulated inner strength.

Programming development experience, the inner strength of overcoming countless difficulties (errors), and the most important last experience!! That is teaching experience.

Even if you have developed it for decades, if the speaker cannot convey it well to the students,

(To put it simply, I'm good with words^^),

He's just a good technician.

That's a given. This is my personal experience, based on decades of meeting hundreds of web developers, designers, hackers, security experts, and game developers.

For example, when I was teaching at a famous academy in Gangnam, I met countless top developers like Sam*, Neck*, and N*. Their skills were truly awe-inspiring. So, over drinks, we often had the opportunity to chat frankly with them. I often asked them, "Why don't you teach, given your incredible skills?" After all, they must be quite valuable.

The consistent answer was, " There are people who are good at technology and can convey it ."

The ability to convey content is innate. And it goes without saying that it requires a wealth of experience to support it.

Yes. That's why not just anyone can teach. Teaching is something where even if you try to lie, it's immediately obvious.

There may be many people with good skills, but it is very rare to find someone who can convey them.

This course is based on decades of experience teaching Korean students, their habits, and where they make mistakes.

Important things in the lecture are basic grammar, advanced techniques like object orientation, and great speaking skills, but also error handling.

In actual lectures, the number of outrageous errors students make is staggering.

Even worse, sometimes the LAN cable is slightly out of alignment and it doesn't work. Or the font is so small that commas appear as periods. Even worse, there are invisible stealth characters (ghost characters) within the code that prevent the program from running. Sometimes, the file extension is incorrect or hidden, causing the code to be mistaken for a plain text document.

You might think this is a truly absurd situation, but in a real-world development environment, even such things need to be taken into consideration. It's something you can learn by staying up all night just for that one thing.

There's a reason so many developers stay up all night with their beacons on.

So, considering all of this, I started thinking it would be a good idea to create a lecture that could proactively reduce the error rate . When selecting sample code, I thought it would be great to carefully select only the best lecture samples that students found most understandable and that could also reduce their error rate, and include them in the video lectures.

Until recently (December 2014) The reason I've continued to teach programming courses (Java, JSP, Spring Boot, C, C++, Python) is because I've been curious about whether students today and past generations have the same difficulties when learning programming. The conclusion is that it's the same regardless of generation.

Therefore, going forward, we plan to provide lectures that will help reduce error rates and facilitate faster learning by applying the big data we have collected so far.

[Instructor Introduction]

Hello~!! I am an instructor who has been teaching IT for about 20 years.

Currently, my main job is translating IT documents and producing video lectures.

When I was a child and going to school, I just wanted to learn about security and hacking (I really had no basic knowledge^^) and I never thought that it would lead me to where I am today.

That's how my relationship with IT technology started, and continued. In the 90s, I was researching various hacking techniques with underground hackers. Then, I worked as a white hat hacker for a while , unintentionally, because my acquaintances (ERP designers) asked me to check the security risks of the computer system (ERP) operated by their company. ^^

It was so long ago that I remember that the term "white hacker" didn't exist in our country at the time.

Because at the time, they were considered as people who only appeared in novels^^

Anyway, I lived with such an interest in hacking and security that at the end of 2008, I had the opportunity to study abroad in Australia for a while, and while I was there, I made an iPhone game with some people and sold it.

When I returned to Korea, smartphones were already popular in the country, so I remember occasionally making games and selling video lectures on game production on domestic platforms.

(* Lectures on iPhone game production/release in Korea around 2010)

Then, around 2015, I happened to find out about overseas video lecture sites, and I became interested in them, so I started releasing lecture content such as "Web Security," "Simulated Hacking Penetration Technology and Defense Techniques," and "C Programming Fundamentals."

I remember the first release being at the end of 2016. Even now, looking at the DVD backups of the content I released back then brings back fond memories. It also makes me realize how much time has passed. I continued to upload lectures to Udemy until recently (early 2024), and currently, only the two oldest lectures remain (web security-related lectures).

Over the years, I have lectured in numerous places, but to put it roughly,

National Police Agency Cyber Investigation Bureau [ formerly Cyber Investigation Unit ] - Unix/Linux Server Simulated Hacking and Infiltration Lecture

SAP Korea - Government-funded lectures

Green Academy Gangnam Branch - Government-funded Unity Game Development Course

Unity Korea - Government-funded Game Development Course

Daegu University - Mobile Game Development Course

Jeonju University - Mobile Game Development Course

It's like this.^^

Thank you for reading my self-introduction post, which was like a self-introduction post on Job Korea. I will continue to create many interesting lectures and post them on great sites like " Inflearn ."

I'm so proud and happy that we have such a sophisticated and great video lecture platform like " Inflearn " in our country .

Well, I hope my lecture will help you get started with programming.

I think I'll end it here~~^^

thank you
