In java, I have a situation : I wrote 3 classes A, B, C, class B extends class A and class C extends class B.
There is a method X() in class A, then I override in class B and override in class C, again.
Now declare a variable M type C. How could I call M.X() in which X() is belonged to class A.
Really need help :)
I code in java, using JDK 1.6.0
