Bhargav Reddy Dagumati · Answer

Yes, It can throw a RuntimeException. RuntimeException and It's childs are Unchecked Exceptions.
When a parent class throws a checked exception that means overridden method, overriding method in child class it's optional to throw checked exception. 
If overriding method throws a checked exception that should be same as overridden or it's child.
In above question it can throw a unchecked exception.

The overriding method can throw any unchecked (runtime) exception, regardless of whether the overridden method declares the exception or not.
