My experience, moving from C++ to Java to Python as the language I use
every day at work:
C++ is extremely complex. The good side of this is it gives you
tremendous control - final, const, pass by reference or value, memory
allocation, etc, etc. The bad side is that it is a lot to think about -
should this parameter be const? who is going to deallocate this object?
and there is a lot of room for error, whole books have been written on
the topic (e.g. Effective C++ which even has a sequel).
Java is less complex and flexible than C++. At first I missed the
control of C++, then I realized that it wasn't really buying me much and
that the cost was too high - coding Java is much less work than coding C++.
Then Python. Python takes away even more low-level control. And I don't
miss it at all. My Python programs work just fine without static typing,
Python is simple and flexible and just does what I want with no fuss.
Java is a heavy straightjacket. C++ is inconceivably complex.
So relax and enjoy it, the only risk is that you will never want to
touch Java and C++ again.
