Re: Types of constructors

A private constructor is a constructor for a class that no one outside of
the class (and it's descendents) can call.
Useful if you don't want anyone to create an object of the class type (other
than a descendent or the code in a static method).

In simply factory method pattern, you may place the factory method in the
class that is being created. The factory method would call the private
constructor.
Singleton is often implemented this way as well.
