What is the Difference Between Polymorphism and Inheritance?
🆚 Go to Comparative Table 🆚The main difference between polymorphism and inheritance lies in their purpose and application in object-oriented programming. Here are the key differences:
- Inheritance:
- Inheritance is a concept where a new class (derived class) is created that inherits properties and methods from an existing class (base class).
- It supports the concept of code reusability and reduces the length of the code in object-oriented programming.
- Inheritance can be single, hybrid, multiple, hierarchical, and multilevel inheritance.
- It is applied to classes.
- Polymorphism:
- Polymorphism allows objects of different classes to be treated as objects of a common superclass, enabling a single function or method to represent multiple forms or behaviors.
- It enables objects of different classes to be treated as objects of a common superclass, allowing for flexibility and dynamic method dispatch at runtime.
- Polymorphism can be defined in multiple forms, such as method overloading (compile-time polymorphism) and method overriding (run-time polymorphism).
- It is applied to functions or methods.
In summary, inheritance is a concept that promotes code reusability and hierarchical relationships between classes, while polymorphism allows for dynamic method dispatch and flexibility in handling different object types. Both concepts are essential in object-oriented programming, but they serve different purposes and operate at different levels.
Comparative Table: Polymorphism vs Inheritance
Here is a table highlighting the differences between polymorphism and inheritance:
Inheritance | Polymorphism |
---|---|
Inheritance is a concept where a new class (derived class) is created that inherits features from an existing class (base class). | Polymorphism allows a task to be performed in multiple forms or ways, and it is applied to functions or methods. |
Inheritance is mainly applied to classes. | Polymorphism is mainly applied to functions or methods. |
Inheritance supports the concept of code reusability and reduces code length in object-oriented programming. | Polymorphism allows the object to decide which form of the function to implement at compile-time. |
Types of inheritance include single inheritance, multi-level inheritance, multiple inheritance, hybrid inheritance, and hierarchical inheritance. | Types of polymorphism include compile-time polymorphism (method overloading) and run-time polymorphism (method overriding). |
In summary, inheritance is a concept that allows a class to inherit properties and methods from another class, while polymorphism enables a single function or method to have different implementations or overloads.
