Nullpointer exception

hello,

Code:

---

import java.io.*;
public class ArrayExample
{
        static void add()
        {
                int k=9;
                int v=8;
                int r=k+v;
                System.out.println(r);
        }
        public static void main(String args[])
        {
               
                ArrayExample ar[]=new ArrayExample[5];
                ar[0].add();
                ar[1].add();
                ar[2].add();
                ar[3].add();
                ar[4].add();
               
        }

}

It is giving NullpointerException, why?

You are trying to access a field or method of an object which hasn't been set. From the compiler message, identify the line that is giving the exception and examine where each reference is being set. If you have any problems, post the line, with each reference and where you think you have set it.

You sure that you ends with a NullPointerException?
