What is encapsulation?

Posted By :Subhransu Sekhar Jena     Posted Date :October 31, 2014    Points :40   Category :OOPS 
Encapsulation is the ability to contain and control access to a group of associated items. Classes provide one of the most common ways to encapsulate items. Encapsulation allows you to control how the data and procedures are used. You can use access modifiers, such as Private or Protected, to prevent outside procedures from executing class methods or reading and modifying data in properties and fields. You should declare internal details of a class as Private to prevent them from being used outside of your class; this technique is called data hiding.One basic rule of encapsulation is that class data should be modified or retrieved only via Property procedures or methods. Hiding the implementation details of your classes prevents classes from being used in undesired ways, and lets you to later modify such items without risk of compatibility problems.
