During overriding a method covariant return types is allowed to get a valid override. Is there any similar rule for the arguments of the method as well?

For eg.

public void function(Object o); - Super class

public void function(AnyClass ac); - Sub class

Does the above is a valid override or is it a overload or an error.

Thanks in Advance,
-Jerry.

It's plain old overload. Don't forget that if there is a class/subclass relationship, then the method with most specific parameter type will be called.

I guess its a overload

But I would also wait for some one to say that confirmed...

Thanks,
Neo
