The Vehicle class is defined in the code snippet provided and serves as the base or parent class from which other classes can inherit properties and methods.
A subclass is a derived class that inherits properties and behaviors from its superclass (parent class). Continuing with our analogy, Car would be considered a subclass because it inherits from Vehicle.
A superclass is another term for parent class – it's the original or base class from which other classes inherit properties and methods. In our analogy, Vehicle would be considered the superclass.
Inheritance is the mechanism through which one class acquires properties and behaviors from another class. It allows for code reuse and promotes hierarchical relationships between classes.
