No, I don't want to say that way or other way.
Nowadays, we hear a lot of crazy things in a dispute about langauge to write your code. First of all, you have to always keep in mind one phrase:
Programming is not a code - it is the algorithm
Let's mark some visible advantages and disadvantages of them:
It is easier and faster to write cross-plattform applications on Java
It is easier to write multithreaded applications on Java, but faster on C++
When you work extensively on memory, then faster is C++
C++ is good, when your perfomance and memory is critical (large calculations and etc.)
Java is easier to study and faster to write a code
C++ is too strict. One small mistake can make a fatal lose in "game". Some people compare it to "playing chess"
There a lot of libraries for C++, that allow writing "beautiful" and fast GUI
A lot of desktop applications are still being written on C++
Some say, that Java is a good start, but not "continue". C++ compilation is generic for every plattform, but not Java.
So C++ is merciless. How much time do you need to make an ideal code?
Have I marked everything? Of course, no. There is no general answer to this question, everything is individual. Every language is good and needed today as well. In conclusion, I wanna say NOT "C++ vs Java", but "C++ and Java" (Because of JNI, you can make one good of two)
I really want to hear your opinion on these points and I really want you to write your suggestions in comments to discuss.
Good luck in your job!
