The document discusses encapsulation in object-oriented programming. Encapsulation is the technique of making fields in a class private and providing access to them via public methods, protecting the data from being randomly accessed. It hides the details of how the object works internally while only exposing its behaviors externally. Access modifiers like private, default, protected, and public determine which classes can access fields and methods. The conclusion emphasizes that encapsulation hides how the state is stored and what happens inside behaviors from external classes. Two assignments are provided involving displaying student data and adding additional attributes to a class.

ENCAPSULATION
o Encapsulation is the technique of making the
fields in a class private and providing access
to the fields via public methods
(INFORMATION HIDING & INTERFACE TO
ACCESS DATA)
o Encapsulation also can be described as a
protective barrier that prevents the code
and data being randomly accessed by other
code defined outside the class.

Conclusion
o Hiding the details of how
the object works: The only
part of the object that is
accessible to the outside
world is its behaviors.
What happens inside those
behaviors and how the
state is stored is hidden
from view.
