In
computer science, the
yo-yo problem is that programmers need to scan the
inheritance graph[?] to understand the control flow of a program. It often happens in
object-oriented programming. The term is derivered from up-down movement of a toy
yo-yo.
Most practices of object-oriented programming recommend keeping the inheritance graph as shallow as possible to avoid this problem. Some additionally advise the use of composition[?] instead of inheritance.
