	6.8.7.	Member Classes Access Modifiers
	6.8.8.	Static Inner Classes
	6.8.9.	Methods of a static inner class cannot use the keyword this (either implied or explicit)
	6.8.10.	Create an instance of a static inner class without the need for a current instance of the enclosing class
	6.8.11.	Classes Defined inside Methods
	6.8.12.	Classes declared in methods cannot be marked as static.
	6.8.13.	An object created from an inner class within a method can have access to the final variables of the enclosing method.
	6.8.14.	Use new C().m1() to invoke the m1() method of a newly created C object.
	6.8.15.	An instance of an inner class cannot be created without first creating an instance of its outer class.
	6.8.16.	Create an instance of Outer and pass it as the enclosing object instance for a new Inner object
