Questions and Answers
What is the concept of inheritance in object-oriented programming?
Inheritance is the process where one class acquires the methods and fields of another class. It allows the creation of new classes based on an existing class, with the new class having combined features of both classes.
What are the alternative names for a subclass in the context of inheritance?
The subclass can also be referred to as the derived class or child class.
How does inheritance provide reusability in object-oriented programming?
Inheritance allows the methods and properties of a base class to be inherited by a derived class, enabling the reuse of code and promoting modularity in the program.
Explain the 'is-a' relationship in the context of inheritance.

Study Notes
Concept of Inheritance
- Inheritance is a fundamental principle of object-oriented programming (OOP) that allows one class (subclass) to inherit properties and behaviors (methods) from another class (superclass).
- It promotes a hierarchical class structure, enabling the creation of a new class based on an existing one, facilitating code organization and reuse.
Alternative Names for Subclass
- Subclass may also be referred to as a derived class, child class, or extending class within the context of inheritance.
Reusability in Object-Oriented Programming
- Inheritance supports code reusability by allowing subclasses to use existing implementations from superclasses, minimizing redundancy.
- New functionalities can be added to subclasses without altering the original code in the superclass, resulting in easier maintenance and updates.
'Is-a' Relationship
- The 'is-a' relationship defines the connection between a subclass and its superclass, indicating that the subclass is a specific instance of the superclass.
- For example, if 'Dog' is a subclass of 'Animal', then it can be said that a Dog is an Animal, showcasing this intrinsic relationship.
Example of Inheritance
- In a scenario where there is a superclass
Vehicle, a subclassCarcan be created to inherit properties like 'speed' and 'color', thus utilizing the existing attributes ofVehiclewhile potentially adding its own specific characteristics.
