What is the use of private variables even though they are accessible via getters and setters from some other class?

Question

Accepted Answer

Private variables provide encapsulation and data hiding.

Private variables can only be accessed within the class they are declared in, providing encapsulation and preventing direct modification from outside the class.
Getters and setters provide controlled access to private variables, allowing for validation and manipulation of the data before it is accessed or modified.
For example, a class may have a private variable for a person's age, but the getter can return a calculated age based on the person's birthdate.
Using private variables also allows for easier maintenance and modification of the class, as changes to the variable can be made without affecting other parts of the program that use the class.
Overall, private variables help to ensure data integrity and prevent unexpected behavior in the program.
