The Power of Encapsulation and Role of Getter and Setter Methods
ENCAPSULATION
Encapsulation in Java is one of the four fundamental Object-Oriented Programming (OOP) concepts. Encapsulation helps in hiding the internal state of an object from the outside world and only exposing the necessary functionalities or methods to interact with that state. This concept is implemented through access modifiers such as public, private, and protected in Java. Encapsulation is used for variables.
