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

You can not override a constructor, however you can make them any access level modifier such as public, private or default. You would want a private constructor for things like a singleton or for a class that's mostly made of static methods and such (i.e Java's Math class)
