I came accros a question in your java rule round up. Which says that a constructor can be declared private. How does this work, I mean how can you create an object from a Constructor declared like this?

You speak out the answer. If you don't want others to instantiat your class, you can make the constructor private. E.g. Math class.

Yes constructor can be declared private

1 -- Once constructor is private we can create object only within that class,we cannot create object outside of the class

2 -- Class cannot be extended also..

U can create an object using a static method of the class that has the private method.
