They are parts of syntax, and any language will have some syntax to learn, and there are always syntactic quirks.
Granted, Python has lighter syntax than Java, but I don't think Java is too verbose for beginner's purposes.
what's out
why is there a period, what does that mean
what's ln
what's pubic
what's static
what's void
what's main
what's String[]
what's args
Java is as verbose as it gets with lots of unnecessary information at a beginner level
I agree that Java shows you more syntax which is intimidating. But the answer to all these questions for all languages is: "it's a special syntax, you should write it exactly as it is. We will learn more details later in the course". There is literally no need to dive in. You wouldn't dive to variadic functions, builtins and CPython implementation details when asked about the name `print` or how it can take multiple arguments, would you?
You get some kind of syntax questions no matter what programming language you teach, even Python. Granted, there may be less with Python in the beginning, but in lots of scenarios the difference is negligible.
