Destroy all constructors!

Has anyone taken the approach of just forgetting about constructors in Java
and instead using a conventionally-named initializer? I'm very, very tired
of having to define (and often edit) the same ctor over and over again in
subclasses. Ctors are not virtual, while an initializer can be.

Cheers, Paul

Taken a subclass PipeLine based on a Vector the initializer in class Vector
would create a Vector object, not a PipeLine. Therefor instance variables
for class PipeLine are not availabe.

Do you really need that much subclasses? Besides, editing a ctor is often
not necessary. It calls the ctor of the baseclass by default. You only need
to initialize the instance variables of that specific class; otherwise,
leave the ctor out.

And you don't even need a constructor for that, you can do:

class Mine {
public String = "";
public HashMap = new HashMap();
}
