package com.example.tree; public class BinaryTreeNode{ private T data; private BinaryTreeNode left; private BinaryTreeNode right; public BinaryTreeNode(T data) { this.data = data; this.left = null; this.right = null; } // getters and setters }
package com.example.list; public class LinkedListNodeThis code defines a generic class LinkedListNode that can be used to represent a node in a linked list data structure. In both examples, the Node class is used as a building block to build more complex data structures. The Node class is typically included in a library or package that provides various data structures and algorithms. The exact package/library may vary depending on the implementation.{ private T data; private LinkedListNode next; public LinkedListNode(T data) { this.data = data; this.next = null; } // getters and setters }
