Information hiding:

This approach of defining classes and objects to control access to data may seem rather elaborate. Why would we want to do things this way?
Later in this unit you will see how inheritance, one of the more advanced facilities related to classes, can facilitate code reuse - that is, you can extend and adapt classes written for one purpose to reduce the effort involved in producing a different software system.

Apart from reuse there is also the advantage of maintainability.Software systems are subject to major changes in their lifetime. Surveys have suggested that as much as 80% of the development effort expended by many software companies is devoted to modifying existing systems.

When you define objects using classes you can restrict access to the instance variables of an object: normally all access to the information stored in an object is via methods. This principle is known as information hiding: the code using an object cannot access or make use of the details of how that object is implemented. This means that when a developer wants to change the implementation of an object (for example, to improve its performance or security) then the instance variables and program code of the methods may change but the external interface to the object - the method names and arguments themselves - does not change. So, there is no need to change any other parts of the software system that invoke the methods of this revised object, as long as the external interface has not changed.
