Hi Friends, can u give me Real Time example for interface
and abstract class.(With Banking Example)
Answer Posted / amit singh
hi pushpa don't go with the book think that
i'm going to tell you what is the imagine
abstract class Human
{
public abstact void eat();
}
thereis osme class is Amit ,Apoorva,and Imarana
they both in hierarchy ofthe Human class theu all extend
this class
class Amit extends Human
{
public void eat()
{
Systm.out.println("eat biryani")
}
}
classApoorva extends Human
{
pulic void eat())
{
Sysetm.out.println("eat food");
}
}
class Imrana extends Human
{
public void eat()
{
System.out.println("eat teh Dosa");
}
}
}
someans to say that theare is same hierarchy means Human
so you want toextends it just for inner world Human
2)
second pointis srise that what you think about the outer
world imagine in outre world there is another class Lizard
it aldso want ot use the functionality eat
that this particular class can extends this i don't think
so and you too
so this is the outer world class this is not in the
hierrachy of the Human so think
i am goin to make the interface for that touse this for
alll world class object whther they are in the hierrrachy
of any superr class are not
interface Nature
{
void eat();
}
class Lizard implements Mature
{
public void eat()
{
System.out.println("eaa mosquito");
}
}
and i'm too going to use this functionality so tell me
isthsii wherer the class in the same hoerrarchy are not
class Amit implements Nature
{
public void eat()
{
System/oput.println("eat any thing");
}
}
}
so this the possible to us this wiytout going any hoerarchy
so if the inner world you should to use abstrac class
but in to use functionality intyhe outer world or inner
world u should to use interface.
i think you got this
