Jump over parent constructor to call grandparent's

Question

The problem is this: I have an abstract class that does some work in its constructor, and a set of child classes that implement the abstract class:

class Abs         


        

Answer 1

You cannot do this in Java. I frequently have students who want to do this, but I have never seen a case where it is really what they wanted to do.

Can you give a concrete example of what it is you want to do and why (your description is too vague) and I am sure a solution can be achieved :-)

Edit:

For a real world example of why you do not want to do this (normally) would be a hierarchy like:

Animal (constructor makes the eyes)
  |
Mammal (constructor makes the lungs)
  |
Human (constructor sets the language)

If the Human constructor could skip over the Mammal constructor then you would wind up with a Human who has no lungs... not very useful.
