in the java the bunary tree node is representations in the using references to other nodes, forming a hierarchical arrangement where each node can refer to at most two other nodes: a left child and a right child.

This reference-based approach establishes connections between nodes, enabling traversal and navigation within the tree structure.

class Node {
int data;
Node* left;
Node* right;

	public Node(key){
	data = key;
	}

}
