You can only set and get values of these variables through the methods of the class. Encapsulation reduces coupling of modules and increases cohesion inside a module because all the pieces of one thing are encapsulated in one place. In Java, a class encapsulates the fields, which hold the state of an object, and the methods, which define the actions of the object. Encapsulation enables a group of properties, methods and other members to be considered a single unit or object. rational behind encapsulation is that if any functionality which is well encapsulated in code i. Encapsulation is used for access restriction to class members and methods. For example capsule i. The role of encapsulation in Java is to group together the data and methods which are acting upon the data while abstraction exposes the interface to a user while hiding the details of implementation. The interface should completely describe how users of the class interact with the class.

Complete encapsulation in java is achieved by making variables of a class private and access to them, outside the class, is provided only through public methods (getters and setters in this case). That’s why encapsulation is known as data hiding. Encapsulation reduce coupling of modules and increase cohesion inside a module because all piece of one thing are encapsulated in one place. Explanation: Encapsulation is the mechanism that binds together code and data it manipulates, and keeps both safe from outside interface and misuse. How to implement encapsulation in java: 1) Make the instance variables private so that they cannot be accessed directly from outside the class. e data (Variables) and and processes performed on that data i.
