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
