hi
why this pgm is getting NUllPointer.

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.
