Making the atributes (variables) in a class private and providing access to those atributes via public behaviours (methods)

Question 2

What are the ADVANTAGES of ENCAPSULATION?

Answer 2

1. Data Hiding
2. Increased Flexibility
3. Reusability
4. Testing code is easy

Question 3

What is DATA HIDING?

Answer 3

The user will have no idea about the inner implementation of the class (implies security)

Question 4

What is INCREASED FLEXIBILITY?

Answer 4

We can make the variables of the class as read-only or write-only depending on our requirement
