One of the most powerful principles of object-oriented technologies is inheritance.It is the ability to define superclass and subclass relationships among classes.Defining inheritance is simply a matter of defining generic (generalization)and specific (specialization)information and procedures.Generic information and procedures apply to all subclasses,which will inherit the information and procedures from the superclass in which they are defined.
