Answer 2

Java does not seem to like the use of an inner class in a static function. If you put the sChecker class in a separate file, it should work.

Answer 3

yes that worked but
the value of i is changed for both the objects :-/
public static void main(String[] args)
{
sChecker s1 = new sChecker();
sChecker s2 = new sChecker();
System.out.println(s1.i);
System.out.println(s2.i++);
System.out.println(s1.i);

}

Result:-
99
99
100

i am able to manipulate a class using an object !!!

Answer 4

The fact that `i` is updated for both objects is normal. A static variable/method is independant of any object. It is a shared variable that can be accessed even without an object (as long as it's declared public. You can also access it with `sChecker.i`.

Answer 5

yup i did that too
