Don’t learn two things at the same time. Using javac without being able to write hello-world doesn’t make sense, so you either need to learn to write hello-world first, or you need to get the file from the teacher.
I strongly disagree with this.
When I learned C (my first programming language), we wrote a .c file in a text editor and compiled them with gcc from a command line. This gave me a much better understanding of the process of writing (and using) a program than an IDE ever could have. I have, since then, learned other languages, and spoken to many people who were learning, or had learned, etc.; and I have noticed a definite pattern, that those who started with the basics (no IDE, no fancy tooling) ended up with a deeper understanding of what they were doing than those who started with the IDE and all that.
You can learn the advanced tools later, but you absolutely should “learn two things at the same time”, if those two things are “the thing you’re trying to do” and “the simple, basic way to do that thing”.
