Following is information about how to create a clean inheritance model and minimize problems when code is upgraded:

Each class must have a single public construction method unless the class is abstract. If no initialization is required, use a static construct method. Otherwise, use a static new… method (the default constructor (new method) for the class should be protected).
Each class should have at least one static construct method method.
Each class should have at least one static new… method.
Each class should have a new method (the default constructor). This method should be protected.
Create accessor methods to get and set class variables.
Create init methods to carry out any specialized initialization tasks that should be carried out after instantiation.
