Enables data abstraction, allowing objects to be treated as a single unit.Increases modularity and maintainability by making it easier to change the implementation without affecting other parts of the code.

Improves security of an object’s internal state by hiding it from the outside world.

Output 7310805450 MD FAIZ 100000.0 Advantages of Encapsulation in Java:

Testing code is easy: Encapsulated code is easy to test for unit testing.

Reusability: Encapsulation also improves the re-usability and is easy to change with new requirements.

from the above program or if we wish to make the variables write-only then we have to omit the get methods like getName(), getAge(), etc. If we wish to make the variables read-only then we have to omit the setter methods like setName(), setAge(), etc.

Increased Flexibility: We can make the variables of the class read-only or write-only depending on our requirement.

The user will only know that we are passing the values to a setter method and variables are getting initialized with that value. It will not be visible to the user how the class is storing values in the variables. The user will have no idea about the inner implementation of the class. Encapsulation also provides a way for data hiding.

Data Hiding: it is a way of restricting the access of our data members by hiding the implementation details.

It is more defined with the setter and getter method.

Encapsulation can be achieved by Declaring all the variables in the class as private and writing public methods in the class to set and get the values of variables.

As in encapsulation, the data in a class is hidden from other classes using the data hiding concept which is achieved by making the members or methods of a class private, and the class is exposed to the end-user or the world without providing any details behind implementation using the abstraction concept, so it is also known as a combination of data-hiding and abstraction.

Technically in encapsulation, the variables or data of a class is hidden from any other class and can be accessed only through any member function of its own class in which it is declared.

Another way to think about encapsulation is, that it is a protective shield that prevents the data from being accessed by the code outside this shield. It is the mechanism that binds together code and the data it manipulates.
