Object Encapsulation is a form of Encapsulation where an object only has access to data stored within itself. This means that:
- Objects do not have access to data in other instances of the same class.
- Objects do have access to the data of any underlying superclass.
- Objects do not have access to data in any other object, unless provided through a method call.
Object encapsulation is the encapsulation method in Smalltalk.
