Class Encapsulation is the most commonly used form of Encapsulation in modern programming languages. Objects are encapsulated by their underlying objects. This means that:
- Objects can see/modify the contents of any other objects that are instances of the same class.
- Objects cannot necessarily see/modify the contents of their superclass (this is language specific; for example it can be allowed in Java by using protected access)
- Objects cannot see/modify the contents of any other objects.
This, or a modified form of, is the encapsulation technique of languages such as C++, C#, Java and Python.
