//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.
 
Don't get me started about those stupid light bulbs.
