Confusion with Object class

We all know that all classes implements Object directly or indirectly. That is why we get all public methods available in Object class.

But as the definition says, if our class extends Object class indirectly and we are able to get public methods like notify(), notifyAll() etc why are we unable to get the protected method clone() of this class even our class extends Object class?

I mean to say either both type of methods must not be available or must be available.

Hope I am clear about my issue?

Can any of you guys explain it?

Regards.
