Java overriding method explain java interview question interviewdot
Rules for overriding a method  in Java ?

  The argument list must exactly match that of the overridden method. If they don't match, you can end up with an overloaded method you didn't intend.

  The return type must be the same as, or a subtype of, the return type declared in the original overridden method in the superclass.

  The access level can't be more restrictive than the overridden method's.

  The access level CAN be less restrictive than that of the overridden method.

  Instance methods can be overridden only if they are inherited by the subclass.

  The overriding method CAN throw any unchecked (runtime) exception,regardless of whether the overridden method declares the exception.
