Java Program to Implement Binary Tree Data Structure

To understand this example, you should have the knowledge of the following Java programming topics:

Example: Java Program to Implement Binary Tree

Output

Binary Tree:  4 2 1 3

In the above example, we have implemented the binary tree in Java. Unlike other data structures, Java doesn't provide a built-in class for trees.

Here, we have created our own class of BinaryTree. To learn about the binary tree, visit Binary Tree Data Structure.

Java Example

Perform the preorder tree traversal

Java Example

Perform the postorder tree traversal

Java Example

Perform the inorder tree traversal

Java Example

Count number of leaf nodes in a tree
