Abstract class has a constructor
Who is going to implement your abstract methods ?

Create a instance need a constructor, but not just only a constructor. All of its components must be defined clearly including abstract method.

I have a dubious and inaccurate way of thinking of an object. For every object which isn't specifically an
(note: O/o) it has two components:
The part from its own class, and
The part from its superclass
If the superclass is abstract, you still need to create that part of the object, and that part will (probably) still need its constructor.
actually instantiate an abstract class directly, but only as an anonymous class which is beyond the bounds of the beginner's forum.
It is sorta covered in the
