institute but you don't know which course is going on in the
institute.But they have printed paper in which all the
courses are written like java,.net etc. This is called
encapsulation.

e.g.-Consider the above example.you have decided for java
the you enters in the institute and tell your course.The
person will explain you about java like duration;fee
structure etc.In simple words abstraction means information
according to the user.

different situation.
