)1. Accessibility modifier(Public/Private/internal) is
allowed for abstract class.
Interface doesn't allow accessibility modifier
2. class can inherit only one abstract class
class can implement more than one interface.
(2) An abstract class can contain fields,
constructors, or destructors and implement properties. An
interface can not contain fields, constructors, or
destructors and it has only the property's signature but no
implementation.
(3) An abstract class cannot support multiple
inheritance, but an interface can support multiple
inheritance. Thus a class may inherit several interfaces
but only one abstract class.
• Interface is used to "implements"; whereas abstract class
is used to "extends".
• Interface can be used to achieve multiple inheritance;
abstract class can be used as a single inheritance.
