Packaging an object?s variables within its methods is called encapsulation.



It is protective wrapper which prevents the data from being accessed by the code outside the the wrapper, the code inside the wrapper can be accessed by a well defined interface<br><br>ex: class is a protective wrapper which binds data and methods together,they can be accessed only though well defined interface(i.e object of that class)

The wrapping of data and function together in a single unit is called encapsulation. It tell how to bind data.this is useful to hide the data which is the new feature added to oops for providing security.

Encapsulation<br>1. Encapsulation is the mechanism that binds together code and the data it manipulates and keeps both safe from outside interference and misuse.<br>2. Encapsulation is as a protective wrapper that prevents code and data from being arbitrarily accessed by other code defined outside the wrapper.<br>3. It binds the data and codes that operates on the data into a single entity.<br>4. Encapsulation protects an implementation from unintended actions and inadvertent access.<br>5. The encapsulation of instance variables is sometimes called as ?Information Hiding?.<br><br>The technique of hiding the internal implementation detail of an object from it?s external views. Internal structure remains private and services can be accessed by other objects only through messages passed via a clearly defined interface. Encapsulation ensures that the object providing service can prevent other objects from manipulating its data or procedures directly, and it enables the object requesting service to ignore the details of how that service is provided.<br>

It is the ability of object to hide its data n methods from rest of the programe.It is one of the fundamental principles of OOPs.<br>for Ex let we have a class called Multiplication defined below<br>Public class Multiplication<br>{<br> private void Multiply(int x,int y)<br> {<br> return x*y<br> }<br>}<br>...<br>...<br>Multiplication abc;<br>int Result;<br>Result=abc.Multipy(2,5);<br>now Multiplication is a class having fumction Multiply as one of its function and abc is the object of the class and this class is used to access the multiply function n there is no other source to access the function multiply hence no one but only object have the power to access the member function of class hiding it from the out side world.

Encapsulation is the process of Binding data in a single class type variable. This concept is just like binding medicine in single capsul.

Encapsulation is used for data hiding. By using encapsulation, operations on datas can be performed through well defined interfaces. This ensures impossibility of inadvertent change of data. For example member values of an object can only be modified through its member methods. In C++, declaring a function friend of a class makes it feasible to access the class data. Java don't have any such concept and seems more objective in this sense.
