Write code to construct instances of any concrete class, including normal top-level classes and nested classes.
Supplementary Objectives
State the kinds of nested classes and interfaces that can be defined.
Identify the context in which a nested class or interface can be defined.
State which accessibility modifiers are allowed for each category of nested classes.
State which nested classes create instances that are associated with instances of the enclosing context.
State the access rules that govern accessing entities in the enclosing context of nested classes, and write code that uses the augmented syntax involving the this keyword for this purpose.
State whether a definition of a nested class can contain static and non-static members .
Write code to instantiate nested classes, using the augmented syntax of the new operator.
Write code to show how nested classes can be imported and used.
Distinguish between the inheritance hierarchy and the enclosing context of any nested class or interface.
Write code to implement anonymous classes by extending an existing class or by implementing an interface.
