Design Pattern Introduction for Beginners | Encapsulation | Part -3

What is Encapsulation? Encapsulation describes the ability of an object to hide its data and methods from the rest of the world. Encapsulation in Java hides the inner details of a class and provides controlled access to its functionalities. For example, in a BankAccount class, encapsulation allows us to protect private variables like accountNumber and balance. It ensures secure access to operations like depositing, withdrawing, and retrieving the account balance. How to achieve Encapsulation in Java? 1. Declaring the instance variable of the class as private. 2. Provide the public setter and getter methods in the class. Advantage: Encapsulation promotes code organization, data protection, and code reusability. #designpatterns #java #lowleveldesign #softwareengineering #objectorientedprogramming #encapsulation
