Can a constructor in Java be private?

Question

Can anyone help me is there anything called private constructor in Java? And why it is been used?

Answer 1

Yes, there is a private constructor in Java. Basically, it is used for three major cases are:

1. It helps to prevent instantiation outside the object in the case of singleton, factory method, static-methods-only class.

2. Also, it helps to prevent subclassing.

3. It helps in the case of overloaded constructors.

I hope this will help.
