Can you have a constructor in abstract class?

Answer Posted / abdul hannan

Yes. We can have constructor in an abstract class but we can
not directly instantiate it. If the abstract class have no
argument constructor, it will automatically call by the
constructor of subclass through constructor chaining. If
abstract class have constructor with argument, then we need
to call it by super() and pass the argument in it.
