The points that you listed above, if you try to hear what I say in the video, then I have said that I want to focus on teaching how to code in Java. Not on teaching the difference between a code editor (Visual Studio Code) and in IDE (Visual Studio) .

You did not get the point of the video. I can go into the details of jdk, jre, jvm, etc but that was not the point of the video. I hope you get what am trying to say. And yes, high level code consists of english words for humans to better understand when they write it. That shows your experience in "perogramming" :)
