A significant strength of object technology is the ability to reuse classes and objects that have been previously defined. One way this is possible is when a new class needs to be modeled that is an extension (or specialization) of some class that has already been modeled (and perhaps implemented). A class that acts as a ‘parent’ for a more specialized class is called a superclass. A class defined in terms of an existing class only needs to define any new (or different) attributes or operations -- by default it will inherit all the attributes and operations from its superclass.
