* An inner class is similar to a nested class in that it is a class inside another class and is declared using the same syntax as a nested class, except that it is not a static class.  An inner class always contains an implicit reference to the outer object that created it.

* The big difference between an inner class and a nested class is that when an instance of an inner class object is constructed, there is an implicit reference to the outer class object that caused its construction.

* If the name of the outer class is Outer, then the implicit reference is Outer.this.

* The AbstractCollection implements some of the methods in the Collection interface (e.g., isEmpty, clear, add, contains, remove, toArray, toString)
