Difference between Data Encapsulation vs Abstraction

January 12, 2008

Encapsulation has two faces; data abstraction and information hiding. Data abstraction is a type seen from the outside. Information hiding is a type seen from the inside.

 

 

Sometime encapsulation is used to mean information hiding only but I think the definition I gave is better because if you encapsulate something you get both an inside and an outside right.

————— In Short —————-

Abstraction focuses on the outside view of an object (i.e. the interface)Encapsulation (information hiding) prevents clients from seeing its inside view, where the behavior of the abstraction is implemented.
