So most of us know how to access an outer class from an inner class. Searches with those words give oodles of answered questions on that topic. But what I want to know is why the syntax is the way it is.

Example:

public class A
{
    private class B
    {
        public void c()
            {A.this.d();}
    }

    public void d()
        {System.out.println("You've called d()! Go, you!");}
}

Why is it A.this.d()? It looks like this is a static field of class A, but... * am confused *

Forgive me if this is a repeat; like I said, searches with those words give how-answers.
