I was wondering why in java constructors are not inherited? You know when you have a class like this:

public class Super {

  public Super(ServiceA serviceA, ServiceB serviceB, ServiceC serviceC){
    this.serviceA = serviceA;
    //etc
  } 

}

Later when you inherit from Super, java will complain that there is no default constructor defined. The solution is obviously something like:

public class Son extends Super{

  public Son(ServiceA serviceA, ServiceB serviceB, ServiceC serviceC){
    super(serviceA,serviceB,serviceC);
  }

}

This code is repetitive, not DRY and useless (IMHO)... so that brings the question again:

Why java doesn't support constructor inheritance? Is there any benefit in not allowing this inheritance?

Thanks.
