Treelify is a Java library that can be used to convert Java Collections into a tree structure representation. It can also be used to convert a tree structure back to an equivalent Java Collection.
Usage
Treelify treelify = new Treelify();
List<T> myList = new ArrayList<T>();
List<TreeNode<T>> nodes = treelify.toTree(myList);
Collection<T> result = treelify.fromTree(nodes);
