An abstract class without any abstract methods should be a
rare thing and you should always question your application
design if this case arises. Normally you should refactor to
use a concrete superclass in this scenario.
One specific case where abstract class may justifiably have
no abstract methods is where it partially implements an
interface, with the intention that its subclasses must
complete the interface. To take a slightly contrived
motoring analogy, a Chassis class may partially implement a
Vehicle interface and provide a set of core methods from
which a range of concrete Vehicle types are extended.
Chassis is not a viable implementation of a Vehicle in its
own right, so a concrete Car subclass would have to
implement interface methods for functional wheels, engine
and bodywork.
