我应该如何引用 Java 中“祖父”类的函数/void？

Question

I know that I can reference to a function/void of my parent class with super. But what about my grandparent? super.super.void/function?

Answer 1

As long as your class and your parent class don't overwrit it you can simply call it. If it has the right visibility (protected,public or if your subclass is in the same package even package-private)

Answer 2

Let's say we have something like this:
A extends B which extends C and C has a method .method()

So, in this case, B has inherit all the C's methods, and so if A wants to call a method that is in C, it just need to call super.method() , which will call B.method() , which (if it's not been overwritten) is the method that is being inherited by C (obviously check the visibility)
