thfafa5's honest review, From Java 9 to Java 21 course

I listened to the great lecture!! I vaguely thought that I should study Java someday when it was updated, and what changed this time, but I was busy with my current life and the materials were mostly in English, so I was hesitant to set aside time to study. However, since you organized the changes and informed me of them, I was able to listen comfortably and enjoyably! It was nice that you explained the important parts in detail rather than simply listing the changes. ㅎㅎ
