What is a Private Constructor in programming?

[thmueller78]

The main difference between public and private there is that other classes cannot create instances from the class with a private constructor.

[Akshay_M]

A private constructor is a special instance constructor. It is generally used in classes that contain static members only. If a class has one or more private constructors and no public constructors, other classes (except nested classes) cannot create instances of this class.
