This is an extremely over-general question. Surely you don't want one of us to recreate a JNI tutorial since 1) good ones already exist, 2) you should first show the fruits of your efforts that you've already expending researching and studying this subject, and 3) after all we're only volunteers.

Please feel free to come back if you have any specific and *answerable* questions.

Thank u sir about ur comments. Firstly, I'm very sorry about all my false. About JNI, I have alredy do a little research about JNI. What i know about JNI are we must add command #include <jni.h> and JNIEXPORT (File C). after I have done this, I try run the main java but still can't call the C++ function.

All this shows is that you haven't yet studied a tutorial on this subject. JNI is a deep subject that will require hours and days of intense research and study on your part to get up and running. The tutorials are easy to find, and I suggest that you get started.
