+#REDIRECT [[Java/Abstract Class]]
-* element()
-* root()
-* is_root
-* parent
-* num_children
-* is_leaf

-public abstract class Tree {
-   abstract Node root();
-  abstract Node parent(Node n);
-  abstract int num_children(Node n);
-  abstract Node children(Node n);
-  abstract boolean is_leaf(Node n);
-  abstract int length();
-  abstract boolean isEmpty();
-  // positions() - iteration of all Nodes in the tree
-  // iter() - iteration of all elements in the tree
