Encapsulation is the technique of making the fields in a class private and providing access to the fields through public methods. Encapsulation is also called as data hiding.

 

The ability to modify our implemented code without breaking the code of others who use our code.

Encapsulation gives maintainabilty,flexibilty, and extensibility to our code.

The fields of a class can be made read-only or write-only.

A class can have total control over of what is stored in its fields.

A class can change the data type of a field, and users of the class do not need to the changes any of theircode.
