In order to implement an interface (such as Comparable) you need access to rewrite a specific class.
If a certain class is given to you as a 'black box' and you now need some way to use a written sort on it - notice that its a black box thus you cannot rewrite any of its code - you would have to create a new class which would act as a Comparator.
