Constructor just serves to makes operations (like setting a atributte) or call a method when a object is created .
It's not obrigatory to use it but for readability you can leaves empty.
But normally you can always set your attributes (if you have some value to set) with a standart value. It's a good practice.

Wouldn't that make things unnecessarily difficult?
You would need to instanciate the 'empty' object, then 'fill it up' afterwards.
With a constructor you can initialize the object in a single line.
