Abstract means 4 which we cant give a concrete definition
for ex wtz d def for animal v cant give so v say animal as
abstract.
Interface came into existence to facilitate multiple
inheritance
Eg for abstract: animal is a abstract class and it contains
both abstract n non-abstract methods
But remember a non abstract class cannot contain abstract
methods
Suppose consider area as method and it is different for
diff shapes like circle,rectangle,square.... here area vil
b calculated for all d shapes bt their implementation is
diff n instead of callin dat area method again n again v
vil declare it once
Now lets move on to interface
for eg if we give a compliment to girl dat she sings like
lata mangeshkar n here both dat girl n lata are connected
together by a sing method n these both r two unrelated
things and in this case we use interface.....
thank u guys have a nice tym.....
