In this case of encapsulation, the attributes of the Point class have been declared private to prevent direct access to them - a form of "data hiding."  The only way to access the attributes is via the class' accessor and mutator methods.  Users would have no idea of the implementation; they just know the Point class has methods to manipulate data.
