same static field in base-class^sub-class

P 25 [[ java precisely ]] Assume class C extends base class B.

Both B and C declare a static field sf.

Now just understand (and remember, if you can) that each static field exists for each class. For now, don't worry how to access them.

In fact, B's sf is probably invisible in C. I think we seldom need to worry about it.
