Inheritance is one in which a new class is created that inherits the properties of the already exist class. It supports the concept of code reusability and reduces the length of the code in object-oriented programming.
Types of Inheritance are:
- Single inheritance
- Multi-level inheritance
- Multiple inheritance
- Hybrid inheritance
- Hierarchical inheritance
Example of Inheritance:
addition of a+b is:11
Here, class B is the derived class which inherit the property(add method) of the base class A.
Polymorphism is that in which we can perform a task in multiple forms or ways. It is applied to the functions or methods. Polymorphism allows the object to decide which form of the function to implement at compile-time as well as run-time.
Types of Polymorphism are:
- Compile-time polymorphism (Method overloading)
- Run-time polymorphism (Method Overriding)
Example of Polymorphism:
addition of a+b is:11 addition of a+b+c is:6 Class B's method is running
Difference between Inheritance and Polymorphism:
|1.||Inheritance is one in which a new class is created (derived class) that inherits the features from the already existing class(Base class).||Whereas polymorphism is that which can be defined in multiple forms.|
|2.||It is basically applied to classes.||Whereas it is basically applied to functions or methods.|
|3.||Inheritance supports the concept of 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 (overloading) as well as run-time (overriding).|
|4.||Inheritance can be single, hybrid, multiple, hierarchical and multilevel inheritance.||Whereas it can be compiled-time polymorphism (overload) as well as run-time polymorphism (overriding).|
|5.||It is used in pattern designing.||While it is also used in pattern designing.|
