I am building a tree like data structure. What is the expected behavior if I have a method
public Set getSiblingNodes(Node node);
Should this method return a set including or excluding itself?
Thanks!

A:
No. It should contain only it's siblings.
A node is not a sibling of itself.
(Why would you think otherwise?)

The formal definition of sibling is "If node x and node y share the same parent node, they are siblings". If x and y are the same node, that statement still holds true. I agree with you, however.
