Hierarchy (object-oriented programming)
In
computer science's
object-oriented programming, the mapped relationships of
sub- and superclasses is known as a
hierarchy. This can be visualized as an upside-down
tree (or perhaps a
pyramid), the top of which is known as the
root. The issue is more complicated with languages that support
multiple inheritance, where hierarchy can be any graph.
Hierarchy in Java
The root of the java class hierarchy is the object class.
