1.)when a class is said to be Abstract if it contain both
implementation & unimplementation details ie,method with
body(implementation),method with out body(un-implementation).
in a class if any method with out body is said to be
abstract method.then before the class name we should keep
abstract to the class.
2.)An interface is a one which is having un-implementation
details(method with out body),multiple inheritence can be
achieved in java by using interfaces.
