Abstraction

• Abstraction means hiding implementation.
• Abstraction can be achieved by interfaces or abstract classes.
• Abstraction focuses on the outside view of an object (i.e. the interface)
• TV Remote is the real world example of abstraction where we know little bit how to operate it. but does not know how they are implemented internally.

Encapsulation

• Encapsulation means hiding the important features of a class which is not been needed to be exposed outside of a class and exposing only necessary things of a class.
• Encapsulation can be achieved by Access modifiers (Public, Private, Protected).
• Encapsulation focuses on the inside view of an object where it is actually implemented(i.e the class).
• TV contains multiple things inside it – Color tube, connections of Speaker, Channel mechanism. is the real time example of encapsulation where these things does not need to be exposed outside.
