Encapsulation protects the data and methods from external disturbances by restricting direct access to them.

Encapsulation is the process of enclosing data and operations into a class to provide them with a protective barrier. 

Encapsulation binds data and procedures that alter them into a single unit to hide sensitive info from users.

 

 

Data member Encapsulation - 

• By using access specifiers
• Involves making data members private inside a class. 
• Still you can alter or obtain the value of a data member using the Setters and Getters methods. .
  • 
• Encapsulating Methods & Properties: 
  • We can hide the methods usage for internal implementation that should not be accessible to the public by utilizing method encapsulation.  
  • To prevent users from accessing such a method, it should be marked as private. 
  •  

 

 

Class encapsulation 

a mechanism that combines data and methods into a single unit called a class. Encapsulation in C# is like putting your things in a Capsule(class

 

Advantage

• Data Hiding: The user doesn't know the class's inner implementation. 
• Flexibility: We can create class variables read-only or write-only as needed. Make variables read-only by using Get Accessor in the code. Set Accessor is all we need to create variables write-only. 
• Reusability: Encapsulation also improves the re-usability and easy to change with new requirements.
• Testing: Encapsulated code is easy to test for unit testing.
