Doubt with a code

[Vishal Hegde]

class Alpha
{
  int over=1;
}

class Beta extends Alpha
{
  int over=2;
}
class Gamma extends Beta
{
 int over=3;
   public static void main(String args[])
   {
      new Gamma().go();
      
   }

    void go()
    {
       Beta b=new Gamma();
       Alpha a=new Gamma();
    

System.out.println(super.over+""+b.over+""+a.over);
    }
}

//super.over should call variable of alpha 1st shouldnt it?

Then why is that the output is
221

Why isnt the 1st value 1 ?

"super" in super.over only "points up" one class. Since the current class is Gamma that means that super.over means Beta's over - 2.

As for why b.over and a.over are 2 and 1 respectively (in case you don't know): fields (and static methods) are not subject to the rules of polymorphism; the reference type (Beta and Alpha respectively) determine what field (or static method) to use.
