Java Access Modifiers+

You would think that the main Java tutorial on access modifiers would be the final word on Java access modifiers. I have referred to their table enough times.

Java access levels

Modifier	Class	Package	Subclass	World
public	Y	Y	Y	Y
protected	Y	Y	Y	N
no modifier	Y	Y	N	N
private	Y	N	N	N

But one thing that caught me out today was, all methods defined in an interface are public by default. The language specification confirms this.
