If you surround your C++ code with 'extern "C"', it turns off the C++
name-mangler so that you can reference functions by the names used in
your source file:
extern "C" {
void HelloWorld(void) {
cout << "Hello, world.\n";
}
} // extern "C"
You can therefore use the exact same recipe as with native C functions.
Accessing C++ objects and their member functions from Java is more
difficult. While technically possible, it ties you to a particular C++
implementation, since you need to reach under the C++ runtime's hood.
Most C++ vendors reserve the right to change their runtime designs, so
you can even get stuck just using a different version of a compiler.
We therefore can't provide any support for this usage.
