The relationship between a superclass and an inherited class is called an “is a” relationship.
A grasshopper “is a” insect.
A poodle “is a” dog.
A car “is a” vehicle.
A specialized object has:
all of the characteristics of the general object, plus
additional characteristics that make it special.
In object-oriented programming, inheritance is used to create an “is a” relationship among classes
We can extend the capabilities of a class.
Inheritance involves a superclass and a subclass.
The superclass is the general class and
the subclass is the specialized class.
The subclass is based on, or extended from, the superclass.
Superclasses are also called base classes, and
subclasses are also called derived classes.
The relationship of classes can be thought of as parent classes and child classes.
