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.
