//Java program


public class test9


{


private native void main(int a, String[] b);



public static void main(String[] args){



int x =3;



String[] y = new String[3];



y[0] = "PAYMENT";



y[1] = "DATA";



y[2] = "TAPE";



System.loadLibrary("test9");



test9 t = new test9();



t.main(x,y);


}
}




-------------------------------------------------------------------------------
/* C program */



#include
#include
#include
#include "test9.h"
#include




void main(int a, char b[]);
void initial_setup(int a , char y[]);



JNIEXPORT void JNICALL
Java_test9_main(JNIEnv *env, jobject obj, jint a, jobjectArray b)
{



int len = (env) -> GetArrayLength(b);



jobject col;




int i;



const char *y;



for (i=0;i
{



col = (env) -> GetObjectArrayElement(b,i);



y = (env) -> GetStringUTFChars((jstring)col, false);



printf("%s
", &y[i]);




}

(env) -> ReleaseCharArrayElements(b,y,0);



return;
}

/* Output */
