Solid Foundation! Starting Java with Determination - Part 1: Procedural Programming
For those aspiring to be Java-based Spring backend developers, to easily secure a job, we learn Java properly! Rigorously!
I have opened a free lecture. :)
Hello, students.
I am Choi Ho-sung, the "Easygoing Developer."
I have opened a free lecture introducing the 'Thinking Skills Training' system and related content to help those who are starting their programming studies.

I expect that through this course, you will be able to eliminate a significant portion of redundancy across all programming languages. From now on, all courses I create (including revisions) will assume that you have completed this thinking skills training.
If you already have programming experience, try solving them with a light heart over the weekend. If you have a strong will to learn programming, including Vibe Coding, please make sure to "definitely" complete the Thinking Skills Training course. The course is free, and you can take it both on Inflearn and on my own platform (nullnull.co.kr).
And soon, we will be conducting the 'Learning Networks with AWS: From Theory to Practice' course as an online live class. If you are interested, please refer to nullnull.co.kr or the announcements on my YouTube channel. Official recruitment may begin as early as tomorrow (April 24, 2026), and although it is an online live session, the number of participants may be limited.
Thank you as always. 😄
Sincerely, NullNull Developer
