A private constructor means only code within the class itself can instantiate an object of that type, so if the private-constructor class wants to allow an instance of the class to be used, the class must provide a static method or variable that allows access to an instance created from within the class.

I didnot uderstand this point :If the private-constructor class wants to allow an instance of the class to be used, the class must provide a static method or variable that allows access to an instance created from within the class.

Please make me understand this point
Thanks in advance

It's just a plain and clear English sentence, but your native language probably isn't English. I'll try to explain it with code.

An example of where this technique is useful is in the implementation in Java of the singleton design pattern.
