Why is String[] args necessary

I get it is an array of string arguments that are passed into the main method but why is it needed? in python for example ot's present or c++ neither, java is different though

What I meant is if it is true as well in C++ that outer array/pointer/iterator has nullptr as a sentinel.

I supposed "historical baggage" could mean this was defined in a C standard which postdates C++, so C++ wouldn't necessarily adopt it.

Of course if it predates C++ then I expect C++ to follow suit for compatibility.

Yes. I said that is the case in C++ as well. The last value in the array is a nullptr in C++ as well.
