All the classes including the abstract classes can have
constructors.Abstract class constructors will be called
when its concrete subclass will be instantiated.

Answer / aditya ganjiwale
Its there to be able to initialize the abstract class
internal state.
Lets say you would like to assign two variables, you would
have to do this for every implementation, but with
constructors in the abstract class you only need it once:
So every class inheriting only needs to call the
constructor, instead of assigning the values themself every
time.

Answer / ram
Abstract class have the constructor in it just to instantiate its instance variables. Where as Interfaces are not containing any instance variables. That is why, they dont have constructor concept.
