Answer Posted / tarunkumar
Abstract class is a class in which it will contain both the
abstract and non-abstract methods.The abstract class must
be inheritable by another class. In vb.net it will be
defined using mustinheritable keyword.
The syntax is :
Public MustInheritable Class classname
Interface is a class in which it will contain only the
abstract methods. The interface can be implemented or not
by the another class.The functions in interface will be
implemented by the another class which implements the
interface.
The syntax is :
Public Interface interfacename
