Yeah, I had to reread the post a couple of times to make sure I had the sense of it right way 'round.

As for my post upthread, the "you" there was the generalized "you, the reader", not you the poster.  I was writing a post, not an email, so what I said was not meant for anyone to take personally but in the spirit of an essay.

Just in case, you know.

As for the distinction between "nested" (i.e., static) and "inner" (instance) classes, I have been much more sensitive to the fine distinction after encountering the interesting edge case of an inner class that inherits from its containing class and accesses the latter's private members.


package eegee;
public class Outer
{
  private String foo()
  {
    return "Outer.foo() ";
  }

  protected String bar()
  {
    return "Outer.bar() ";
  }

  class Inner extends Outer
  {
    public String foo()
    {
      return "Inner.foo() ";
    }

    public String bar()
    {
      return "Inner.bar() ";
    }
  }

  public static void main(String [] args)
  {
    Outer encloser = new Outer();
    Inner inner = encloser.new Inner();
    Outer outer = inner;
    System.out.println("encloser: " + encloser.foo() + encloser.bar());
    System.out.println("   outer: " + outer.foo() + outer.bar());
    System.out.println("   inner: " + inner.foo() + inner.bar());
  }
}

Of course, @Override helps here.
