Binary Tree Implementation

In Java, a Binary Tree can be implemented using the TreeNode class to represent each node with reference to its left and right children. Postorder traversal can be implemented recursively by visiting the left subtree then the right subtree and finally the root.


Java Program to Perform the Postorder Tree Traversal

The Binary Tree can consist of nodes where each node contains the value and the references to its left and right children. The structure is organized hierarchically with a single root node at the top and each node having at Most Two Children.

In this article, we will learn to perform Postorder Tree Traversal.
