If you use final keyword then you are bound to initialize that variable at declaration time, this behavior guarantees that when class Inner will use x, x will have some value, so it can copy that value to s.

If you do not use final then there is no guarantee that when inner class will use x, x will have any value.


how is this right?

final int x;
x=10;

is legal then how is initilizing at the declaration time right?

this was from one of the previous posts of Punit.....
