This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
An inner class is normally only used with it's outer class. You can create instances of it in other classes by using an instance of the outer class. You can extend the inner class in other inner classes in the same outer class.
An inner class (a nested class that is not static) is tied to an instance of its enclosing class.
However, note that inner classes can inherit independently from the outer class. When a base class is extended and its inner classes are re-declared in the subclass (similar to a shadowed variable), these nested classes do not automatically inherit from the derived class.
