What is a Final Class in Java? | Java Final Class Explained | Java Tutorial

Welcome to this Java tutorial where we explore final classes in Java programming!

In Java, a final class is a class that cannot be subclassed or extended by other classes. When a class is declared as final, it means that no other class can inherit from it. Final classes are used to enforce class immutability and prevent unintended modifications to the class behavior. In this video, we'll dive deep into understanding final classes and their significance in Java programming.

Key topics covered in this tutorial include:
- **Understanding Final Classes**: Explanation of what final classes are and how they work in Java.

- **Purpose and Benefits of Final Classes**:
- Explore the reasons for using final classes to prevent subclassing and ensure class integrity.
- Discuss the advantages of final classes in terms of performance optimization and security.

- **Final Class Declaration**: Learn how to declare and use final classes in Java to achieve class immutability.

- **Impact on Inheritance**: Understand the implications of final classes on class hierarchy and subclassing.

- **Best Practices for Using Final Classes**: Explore best practices for designing class hierarchies and utilizing final classes effectively.

- **Examples and Demonstrations**: Walk through practical examples to illustrate the usage and benefits of final classes in Java programming, showcasing different scenarios and use cases.

By the end of this tutorial, you'll have a solid understanding of how final classes work in Java and how to leverage them to design secure and immutable class structures.
