    Default how to convert this into JNI code

    Hello i now this is basic and i hope some one helps please read.

    Sample #1
    --> Start
    //this is a java code that calls the JNI to print "Hello World"
    class HelloWorld {
    static {
    private native void print();

    public static void main(String[] args) {
    new HelloWorld().print();

    #include <jni.h>
    #include <stdio.h>
    #include "HelloWorld.h"

    Java_HelloWorld_print(JNIEnv *env, jobject obj)
    printf("Hello Java Native Interface.\\n");
    --> End

    And i want to do is that java will get the value of string variables from JNI and it will print hello world. for example in using java like this.

    Sample #2
    --> Start
    public class classOne {
    public static void main(String[]args){
    String stringfrom_classTwo = classTwo.pblic_static_str();

    // how to convert classTwo into a JNI?
    public class classTwo {
    public static String pblic_static_str(){
    String str = "Hello World";
    return str;
    --> End

    How to convert Sample #2 into JNI code thanks?
