Encapsulation

Dive into Design Patterns

Identify the aspects of your application that vary and separate them from what stays the same.

• The ability of an object to hide parts of its state and behaviours from other objects, exposing only a limited interface to the rest of the program
• To encapsulate something means to make it private and only accessible from within methods of its own class.
  • You can isolate the parts of the program that vary in independent modules, protecting the rest of the code from adverse effects
• The goal of encapsulation is to minimise the effect caused by changes
• Interfaces and Abstract Classes/Abstract Methods are based on the concepts of abstraction and encapsulation.
