However, the subclass leaves the concrete class as is and does not attempt to instantiate the superclass.

Similarly, a subclass destructor must call its superclass destructor after it has completed its own resource reclamation.

However, subclasses are not limited to the state and behaviors provided to them by their superclass .

The class was made abstract when its superclass is not abstract.

If T doesn't include an annotation, then the type checker disallows its use as the superclass.

In a subclass you can make assumptions about the internal state of the superclass when the method you override is getting called.

Also, each subclass inherits methods from the superclass.

Classes are arranged in a hierarchy, so that a subclass can inherit behavior from its superclass.
