If the user attempts to add an element to the set that violates this constraint the add call will throw a classcastexception.
Java tree standard library.
In java tree each node except the root node can have one parent and multiple children.
For the high level users the rules of data organization do not make any difference in its usages.
The treeset and treemap classes are the most obvious implementation of binary tree data structure in the java api library.
Specifically i need to represent the following.
To display tree structured data use the jtree control in java swing at first create a node in the tree defaultmutabletreenode node new defaultmutabletree.
We will create a class node that would represent each node of the tree.
I am not really interested in sorting.
The map is sorted according to the natural ordering of its keys or by a comparator provided at map creation time depending on which constructor is used.
The sub tree at any node can have an arbitrary number of children.
Or maybe get all the leaf node from a tree.
But the tree structure is slightly more complicated and inefficient than its non tree or linear counterparts like hashset and hashmap due to the numerous rules to maintain.
Is there an exisitng java library that will let me add root node child node or for example get a child node from a tree and then add child to those nodes as well.

All i want is a tree like structure since i am creating an org chart.
Provides library support for the java programming language annotation facility.
Algorithms are adaptations of those in cormen leiserson and rivest s.
Root node doesn t have a parent but has children.
All elements inserted into the set must be mutually comparable by the specified comparator.
Constructs a new empty tree set sorted according to the specified comparator.
Node class has a data attribute which is defined as a generic type.
A red black tree based navigablemap implementation.
Each node after the root and it s children will have string value.
