Calling super super class method

by

You can’t even use reflection. Something like

Class superSuperClass = this.getClass().getSuperclass().getSuperclass();
superSuperClass.getMethod("foo").invoke(this);

would lead to an InvocationTargetException, because even if you call the foo-Method on the superSuperClass, it will still use C.foo() when you specify “this” in invoke. This is a consequence from the fact that all Java methods are virtual methods.

It seems you need help from the B class (e.g. by defining a superFoo(){ super.foo(); } method).

That said, it looks like a design problem if you try something like this, so it would be helpful to give us some background: Why you need to do this?
