Example 1:In the below example, we will set two fields as private name and email in class UserDetails. So these fields can only be access within this class and no outside class can access it. Also here we will create public methods getter (Ex. getName()) and setter (Ex. setName())...
This way data can only be accessed by public methods thus making the private fields and their implementation hidden for outside classes. That’s why encapsulation is known asdata hiding.Lets see an example to understand this concept better. Key Concepts of Encapsulation in Java: Private Variables...
The encapsulation mechanism is used by very popular design patterns, in order to provide a specific functionality. For example, theFactory Patternaims for creating objects, without exposing the implementation logic to the client. On the other hand, theSingleton Patternis used to ensure thatat most ...
Increased Flexibility: By controlling access to the fields of a class, you can change the internal implementation without affecting the external code using the class. Improved Maintainability: Encapsulation helps in maintaining the code by keeping the fields private and providing public getter and setter...
Data hiding is a way of restricting the access of our data members by hiding the implementation details. Encapsulation also provides a way for data hiding. We can use access modifiers to achieve data hiding. For example, Example 2: Data hiding using the private specifier class Person { // ...
Class encapsulation type, as the name suggests is part of class which makes use of various composite API’s (Application Programming Interface) which helps in doing the internal Implementation as per the requirement. Same and the major logic of the application will be holded by the interface itse...
Whatever changes, encapsulate it“. It has been quoted as a famous design principle. For that matter, in any class, the changes can happen in data in runtime and changes in implementation can happen in future releases. So, encapsulation applies to both i.e. data as well as implementation....
Abstraction happens at class level design. It results in hiding the implementation details. Encapsulation is also known as “Information Hiding”. An example of encapsulation is marking the member variables private and providing getter and setter for these member variables....
capable of being used to build sophisticated applications on both the clientandthe server. However, the more sophisticated the implementation, the bigger our responsibility to create maintainable and flexible code. In this article, I demonstrate how to use one of the pillars of object oriented progr...
