What is the better course to start obj oriented programming between java and c++

Answer 1

Java because it is simple object oriented (not 100% ) while C++ is semi or hybrid object oriented language because the main() function is not inside the class.

Answer 2

You need to decide that for yourself. I prefer C++ as I've programmed it for 23 years. While Java, I've just learnt. They are similar so code from one can run with little to no change in the other.
