Binary Tree
- There can only be two child nodes of a single node, except the leaf nodes
- A leaf node does not have any children
- Each node has a field to store data, i
.e, the value of the node.- Each node has a pointer to the left child node and a pointer to the right child node

How to create a hierarchy in Java?
In hierarchical data, each of these “children” nodes has only one “parent,” but each parent can have multiple children.
The first node, at the top of the hierarchy, is called the root node.
When information needs to be retrieved, the whole tree is scanned from the root node down..

What is the hierarchical data model structure?

This concept uses a hierarchical tree structure to organise the data.
The hierarchy begins at the root, which contains root data, and then grows into a tree as child nodes are added to the parent node..
What is the hierarchy of data structure?
Hierarchical data is a data structure when items are linked to each other in parent-child relationships in an overall tree structure.
Think of data like a family tree, with grandparents, parents, children, and grandchildren forming a hierarchy of connected data..
- A hierarchical data structure is a way of organizing data in a tree-like structure, where each element in the structure has one parent node and zero or more child nodes.
In a hierarchical data structure, the top-level element is known as the root node, which has child nodes that are connected to it.
