First Java project. What to write while studying?

Question

Java

I have taken up Java several times already and every time I come to some kind of dead end. I think it's all because of the lack of practice. In principle, I am familiar with the basics of programming. (Variables, arrays, loops, etc.). And here with OOP it is necessary to understand still well. So this is the very essence of the question: what exactly can be cut in parallel with the study of Java? What to choose as the first project? Keep it simple to start with, but make sure it covers the main aspects of the language. Thanks :)

How do I understand the student? file the university schedule for all courses with a web interface for the admin panel and API for the client

Answer 2

It's better to start with something simple.
