The less restrictive the level, the more expensive change is when it happens and the more coupled the class is with other dependent classes (i.e. The encapsulate class is easy to test, so it is also better for unit testing. Data Encapsulation is a concept of object-oriented programming language, which is a sub-process of Data hiding. The two concepts, one being a part of the other, have different meanings. A protected class property or method has all of the characteristics of a local member, except that it can be inherited; it is visible to subclasses. Encapsulation is an OOP methodology, that bundles the data with the methods operating on that data.
