why this pgm is getting NUllPointer.

hi
why this pgm is getting NUllPointer.

Code:

---

public class Split {
        static Integer intobj;
        static void print(int val){
                int x=10;
                System.out.printf("%d", x+val);
        }
public static void main(String[] args) {
        print(intobj);
}
}

---

You need to initialize intobj.
use:

static Integer intobj = new Integer(10);

Or, declare intobj as an int.
The difference being Integer is an object whilst int is a primative data type.

Regards.
