Encapsulation is a process of wrapping code and data together into a single unit. It is a way to achieve data hiding.

An interface is a blueprint of a class. It has static constants and abstract methods. The interface is a mechanism to achieve fully abstraction in java. There can be only abstract methods in the interface. It is used to achieve fully abstraction and multiple inheritance in Java. Interface also represents IS-A relationship.
