Mechanism to create new classes using existing classes The existing class is called the parent class, or superclass, or base class The derived class is called the child class or subclass As the name implies, the child inherits characteristics of the parent That is, the child class inherits the methods and data defined by the parent class. Once a behavior (method) is defined in a super class, that behavior is automatically inherited by all subclasses
