Encapsulation and Inheritance are two important OOPs concepts.
Encapsulation is the process of binding data and functions that manipulate that data together in a single unit, called a class.
Inheritance is the process of creating a new class by inheriting properties and methods from an existing class.
Encapsulation helps in data hiding and abstraction, which makes the code more secure and easy to maintain.

Final keyword is also used in try-with-resources statement to declare resources that should be closed afte
