How to access a superclass method from a nested class?

Question

I hope this code explains the problem:

class Foo {
    void a() { / *stuff */ }
}

class Bar extends Foo {
    void a() { throw new Exception(\"This is not a         


        

Answer 1

Bar.super.a() appears to work.

Per JLS section 15.12

ClassName . super . NonWildTypeArguments_opt Identifier ( ArgumentList_opt )

is a valid MethodInvocation

Answer 2

You can call any method from the outer class with Outer.this.method().

But methods are resolved at runtime, so if you have overridden it in your subclass, only the subclass method (Bar.a()) can access the original (by calling super.a()).

As you probably discovered, you can't write Bar.this.super.a() -- but even if you could, it would still give you Bar.a(), not Foo.a().
