What do you call a node that has the same parent node?

Nodes with the same parent are called siblings. More tree terminology: The depth of a node is the number of edges from the root to the node. The height of a node is the number of edges from the node to the deepest leaf.

Are the nodes with the same parent?

Sibling nodes are nodes on the same hierarchical level under the same parent node.

Can a tree node have 2 parents?

Yes, you can have nodes have both “children” and “parents”. However that is no longer a tree structured graph, so you will not be able to use a TreeModel – you must use a GraphLinksModel. Whether or not you can use TreeLayout depends on the circumstances.

Can a node have more than one parent node?

No, DOM is a like a tree structure that does not support multiple inheritance by default which means each child node can have only one parent, but one parent can have any number childs.
