How can I implement a binary tree in Java?

To implement a binary tree in Java, you can start by creating a class for the tree nodes. Each node should have a value and references to its left and right children.

Can you show me a simple code example?

Sure! Here's a basic implementation:

class Node {
    int value;
    Node left, right;

    Node(int item) {
        value = item;
        left = right = null;
    }
}

class BinaryTree {
    Node root;

    // Add methods for insertion, traversal, etc.
}

This defines a node and a binary tree class.

What methods should I add for traversal?

You can implement methods for in-order, pre-order, and post-order traversal. Would you like examples of those?
