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

1. No we can't use a constructor out of class because sub class is treat constructor as a method.. without return type.
2. You can use it as a private but if a constructor of a class is private then you cannot make the obj of the respected class into another class.
