RE: What is data encapsulation? What does it buy you
The most common example I can think of is a javabean. Encapsulation may be used by creating 'get' and 'set' methods in a class which are used to access the fields of the object. Typically the fields are made private while the get and set methods are public.
Encapsulation can be used to validate the data that is to be stored, to do calculations on data that is stored in a field or fields, or for use in introspection (often the case when using javabeans in Struts, for instance).

Encapsulation is a mechanism that combine to gether code and data that it manipulate. It is protective wraper to prevent the access of code and data from out side world or we can say from other class.
RE: What is data encapsulation? What does it buy you
The basic "class cocept" of Java is nothing but Encapsulation. In a class Data members and methods are wrapped / combined. In a class we can specify the variables as private. So for other classes it will not be accessible. Thru member functions / methods only we can access the member variables or modify them. It gives more security for our data.

Encapsulation:wrappering up the data and associated methods into a single unit in such a way that data can be accessed with the help of associated methods.
Encapsulation provides data security. It is nothing but data hiding.
RE: What is data encapsulation? What does it buy you
encapsulation mean data hiding.data correspond to varibles and methods of the class. Data hiding mean: when u make different objects of the same class. The data stored in one object is unaware of the data for other object of the same class. In, this way it gives secure data.
