Procedural Programming Principles and Methods
Basic Java Grammar
IntelliJ Usage and Debugging Techniques
JVM basic structure
For those who don't believe in the saying 'finish it in one go'
We've prepared Java to get you started.
📺 Programming beginners, please watch this! 📺
Although Java is an object-oriented programming language, this course does not cover object orientation.
Instead , we'll delve into procedural programming , which is essential for mastering object-oriented programming. It'll take you over 19 hours!
The process by which Java byte code built with Java is loaded and executed on the JVM .
You'll learn about what the JVM components do while they're running. It's not a deep dive yet, but it's definitely a good introduction.
From how to describe a procedure logically to deciding which of several constants should be a variable .
Train yourself to be able to distinguish between them .
In addition , by presenting design principles along with the theory of functions, you can perfectly establish a foundation for studying object-oriented programming.
※Wait a minute! What is JVM?
JVM (Java Virtual Machine) is a virtual computer that helps run Java programs on a computer.
Just following the code is boring
A beginner programmer who feels like nothing is left in his head
As a backend developer
Job seekers who want to get a job
Because it is a widely used language
I learned it but I don't know the essence
Junior developer with 1-2 years of experience
The Java series, which starts with a strong focus, consists of four lectures.
Appendix 1 and 2 are good lectures to listen to together to grow as a Spring backend developer 🙂
Part 1: Basic Grammar, Procedural Programming
Part 2: Object-Oriented Programming + Data Structures
Part 3: Writing a System Utilization Program
Part 4: Preparing to Move to the Spring Framework
Appendix 1: Understanding Web Infrastructure Technologies and DB
Appendix 2: Advanced SQL
Part 1 is the first course in a curriculum designed for those aspiring to become practical Java backend developers based on the Spring framework . Beyond the grammar of programming languages, this course will help you understand their essence and lay the foundation for becoming a capable developer.
The most challenging topics for beginner programmers are often ones they don't even realize they're struggling with. However , after completing this course, you'll gain the discernment to discern what you're good at and what you're not !
You'll be able to clearly analyze the problem (processing conditions) and think specifically about how to code it . You'll also gain the ability to independently address any errors that arise during the example writing process.
Above all, you can feel that OOP programming is no longer something to be feared, but rather a simple subject to learn.
Even though it is an introductory level, you will learn various structural theories including the JVM structure.
By doing this, you can understand the fundamental workings of applications developed in Java .
This will ultimately bear fruit in the form of failure response skills that are unusual for a newbie when you grow into a working developer.
In class, you will not only learn detailed information about various technical terms, but also learn specific situations in which they should be used.
This is a technical vocabulary skill that is essential for researching and understanding advanced theories on your own.
The basic theory of methods (functions) isn't something to be understood, but rather memorized. While the theory itself isn't difficult to learn, determining which code should be converted into methods isn't.
This lecture provides an easy-to-understand explanation of the principles for easily overcoming such problems and further understanding design patterns .
All class content is based on PPT materials, but the explanations continue as if writing on a whiteboard .
This allows students to see not just one completed result, but You can comprehensively understand the overall flow of the background and reasons for the creation of the structure .
Before learning full-fledged Java programming, we would like to make it clear that this course is aimed at employment .
Based on the instructor's extensive teaching experience, we provide a clear learning roadmap and required time .
We encourage you to establish an appropriate study allocation and schedule from the beginning to avoid wasting time on poor choices.
Learn how to use the IntelliJ debugger in detail. We'll cover simple position breakpoints and even how to leverage conditional expressions for even easier usage.
You can experience practical debugging methods, such as how to distinguish between deep copies and shallow copies using ObjectID , which is assigned to uniquely identify each instance in the JVM .
We provide a variety of practice problems (25 problems) so that you can immediately apply what you learned in class, and you can also check the process of writing the correct code.
Rather than just seeing the correct answer, you can directly observe the process of writing code and experience coding techniques that you cannot learn from general books or lectures.
Operating System and Version (OS): Windows 11
Tools Used: IntelliJ IDEA 2024.2.3 (Community Edition)
PC specifications: Windows 11 OS and IntelliJ can run without any problems
PPT materials used in class (provided as PDF files)
Complete examples and answers to essential practice problems (provided as a zip file)
It's good to know ASCII code, the difference between integer 1 and character '1', and that 65 is 'A'.

We'll also cover CS fundamentals in class! Don't be afraid :)
Who is this course right for?
Student to 'properly' learn Java
Java learner with C/C++ development experience (not necessarily!)
Aspiring Spring backend dev.
Need to know before starting?

Note for prospective students I am a Mac user. I use shortcuts when I breakpoint, but I can do it with the mouse. I memorized the pre-course broadly and shallowly, so I feel like I am talking about it again in this lecture even if I did not attend the lecture to become a computer science major. I don't think it is necessary. ----------------------------------------------------- I only left the method.. Don't be frustrated. You told me not to be frustrated like a snail, but I was frustrated.. Ugh, it's difficult. I will look forward to the next lecture. By the way, if I have over 100 reviews, can I not get a coupon for the next lecture? ㅋㅅㅋ
Wow~! It's almost finished already. First of all, I would like to say that you are amazing. And I appreciate the opinion that wide and shallow... are not necessarily necessary. I think this feedback will be helpful to others. Regarding the lecture coupon... It's not something I can decide, so it's hard for me to answer, but... I will try to find a way to purchase Part 2 of the lecture a little cheaper. It would be helpful if you subscribe to my YouTube channel. Thank you. :)

I decided to take the Java class because it was an elective for my major, and I felt there were limitations to learning it on my own. Since I had encountered C language first, it was difficult to understand Java concepts, but the professor not only explained the differences between C and Java but also specifically pointed out and explained, "While it works this way in native code, Java processes it this way!", which was very helpful. Due to my shortcomings, I regret not getting the grades I wanted on the midterm and final exams, but I think it was helpful just to learn what the Java language is and how it works. If I were to give a tip to students, I recommend going to a library or bookstore, buying a basic Java concepts book that suits you, and studying along with it. Listening to lectures is good, but it might create a misunderstanding of what you've understood, so I recommend reading it in text, listening to lectures, and doing both simultaneously. Don't skip all the codes in the PPT; execute each one at least once and review them. If names overlap, it's good to just create another directory and repeat. Lastly, I recommend asking an AI to generate problems relevant to the topic and solving them yourself.
Perhaps this lecture is optimized for those who are encountering Java after already knowing C. Fortunately, it seems that is exactly your situation. I believe you will be able to understand Java more deeply. Although you may have felt regret about your grades, I am confident that it won't be a big problem once you become a practical developer. Perhaps it may be a somewhat circuitous learning path, but I can tell you that consistently practicing with hands-on exercises, theory, and even problem-solving using AI, as you are doing now, is the right way to go. I am confident you will do well and achieve good results. :)
