Inheritance in OOP languages
// Base class
class Vehicle {
public:
void accelerate() { }
void brake() { }
};
// Inheriting class
class Car : public Vehicle {
public:
void honk() { }
};
int main() {
Car myCar; // Create a Car object
myCar.accelerate(); // Inherited method
myCar.honk(); // Car's own method
myCar.brake(); // Inherited method
return 0;
}
-
This should be a short reminder for students about what inheritance is in other languages.
-
Inheritance is a mechanism where a “child” type gains the fields and methods of the “parent” types it is inheriting from.
-
Methods are able to be overridden as-needed by the inheriting type.
-
Can call methods of inherited-from classes with
super.
