Along with abstaction in java and polymorphism in Java, Encapsulation is a must know concept. In this java tutorial  we will see How to use encapsulation in Java, advantage and disadvantage of Encapsulation and various design patterns and real life problems which makes use of Encapsulation object oriented concept.
