Question

Why can\'t this() and super() both be used together in a constructor?

What is the reason for incorporating such a thing?

Answer 1

There is a difference between super() and this().

super()- calls the base class constructor whereas
this()- calls current class constructor.

Both this() and super() are constructor calls.
Constructor call must always be the first statement. So you either have super() or this() as first statement.
