Can we override a constructor in Java and can a constructor be private?

Question

I would appreciate an explanation for these questions:

1. Can we Override a constructor in Java?
2. Can a Constructor be private?<

Answer 1

Constructor is meant for a class. It cant be overridden under any circumstances. Its like wanting to change Ferrari's factory from BMW's factory (which isn't practical). Surely you can overload to get the functionality you need.

Yes Constructor can be private. By making it private you are not letting the outside world to create an object of it directly through constructor, But singleton pattern uses a public static method to call the constructor of the class and object can be created.
