"Web27 de mai. de 2024 · To build a tree in Java, for example, we start with the root node. Node root = new Node<>("root"); Once we have our root, we can add our first child node using addChild, which adds a child node and assigns it to a parent node. We refer to this process as insertion (adding nodes) and deletion (removing nodes). " - Hierarchy.cut_tree
