Mastering Java 21 [Beginner] - From Basics to Object-Oriented Programming
This is an introductory Java course designed so that even those starting programming for the first time can follow along. You will systematically learn everything from JDK 21 environment configuration to variables, data types, control flow statements, arrays, strings, and the core concepts of Object-Oriented Programming (OOP) such as classes, inheritance, polymorphism, and exception handling. Rather than simply listing syntax, we explain "why it works this way" to help you build a solid foundation.

[Notice] Announcement and Apology Regarding Lecture Upload Delay
Hello, students.
Due to personal health issues, the lecture uploads are currently being delayed longer than scheduled.
I would like to express my sincere apologies to those who are waiting.
I will do my best to resume uploads as soon as possible once my health recovers. I would appreciate it if you could wait just a little longer.
I would like to express my deepest gratitude once again to everyone who always supports me, and I am truly sorry for the inconvenience.
Thank you. 🙏
