- The relationship between super classes and sub classes is known as an inheritance hierarchy. Single inheritance of classes means that each class has only a single `parent' class and that the
Objectclass is the ultimate ancestor of all classes - at the top of the hierarchy. Two classes that have the same immediate super class can be thought of as sibling sub classes. Multiple inheritance of interfaces gives the hierarchy a more complex structure than that resulting from simple class inheritance.
