I want to know whether we can create a Private default constructor in a class. Can anybody explain what is Singleton class?

Yes, it is possible to create a private default Constructor.

If all constructors are private you cannot create an instance from outside that class.

If you create a public static method that always returns the same instance of that class you have used the singleton pattern.

Look at the example:
