abstract class contains all abstract method or all concrete
method or combination of both. we can not directly create
object of abstract class.abstract class methods must
implemented in sub class.
interface contains declared method but does not contain body
of method.like abstract class we can not create instance of
interface.methods defined in interface are public &
implicity called as abstract method & interface must be
implemented in the classes with implements keyword which
contains implementation of methods
