Java OOPC - Polymorphism

 

Polymorphism

 

 

Polymorphism is the process  When Method in the sub class override the Method in the Super class, and do the upcasting after that call the  sub class method though the super class reference.

 

When we have multiple choices inherit the  all classes that need the super class ,after that create the meaningless method. In the end create the object as the upcasting to call sub classes. Then we can call the object for necessary data input.

 

Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows objects of different types to be treated as objects of a common type. This not only enhances code flexibility but also promotes code reusability and maintainability.

 


 In other simply way we can tell polymorphism as the take many forms.

If we come to real world exam below show it simply.



In the example, the `Calculator` class exhibits method overloading by defining multiple methods with the same name (`add`) but varying numbers of parameters. This form of polymorphism enables the class to offer different implementations of the `add` method based on the provided arguments. The `main` method showcases the utilization of these overloaded methods, demonstrating how the `add` method can be invoked with different numbers of arguments, showcasing the flexibility and versatility of polymorphism in Java.





 




Characteristics/Features of Polymorphism in Java


1. Polymorphism allows using the same name for a member or method in a class with different types.

2. The functionality of a method behaves differently in different scenarios.

3. The behavior of a method depends on the data provided.

4. Polymorphism supports implicit type conversion.

 

Advantages:

- Programmers can reuse code through Polymorphism.

- Supports a single variable name for multiple data types.

- Reduces coupling between different functionalities.

 

Disadvantages:

- Polymorphism can lead to performance issues in real-time applications.

- Reduces the readability of the code.

- Some programmers find Polymorphism challenging to implement.
