Question

I want to call both a parent constructor and another constructor in the same subclass. Is this allowed? Also, I understand that this() has some limitations on it (having to be placed first) does super()? Can I place a call to both in the same constructor?

Answer 1

In the same class, yes.

class Stuff extends Object
{
      Stuff ( )
      {
            super ( ) ;
      }

      Stuff ( int x )
      {
            this ( ) ;
      }
}

In the same constructor, no.
super or this has to be the first thing in a constructor.
If super is first, then this can’t be first.
If this is first, then super can’t be first.
They can not coexist in the same constructor.
