A:
Yes. As long as the interface uses the standard C calling convention, Java doesn't really care in which language it's implemented. That means you have to surround the declarations in an extern "C" block if you happen to be writing C++:
#include <jni.h>
#ifdef __cplusplus
extern "C" {
JNIEXPORT jstring MyNativeMethod(JNIEnv *, jobject);
}
#endif
It's up to you whether to implement MyNativeMethod in C, C++ or any other language.
Of course, this is already done for you in the header file generated by javah, extern "C" and all.

You don't define native methods in Java. You define the interface but the actual methods remain outside of your Java application.
