How to design a Node in Tree?
There are three main components of a tree in a node.
1) Integer holding data.
2) Left pointer holding node in a left subtree.
3) Right pointer holding node in a right subtree.
The following design is having data of int type and left,right pointers of a node to the subtrees.
package com.BST;publicclassNode{int data; Node left; Node right;/** * @return the data */publicNode(int data){this.left=null;this.right=null;this.data=data;}publicintgetData(){return data;}/** * @param data the data to set */publicvoidsetData(int data){this.data= data;}/** * @return the left */public Node getLeft(){return left;}/** * @param left the left to set */publicvoidsetLeft(Node left){this.left= left;}/** * @return the right */public Node getRight(){return right;}/** * @param right the right to set */publicvoidsetRight(Node right){this.right= right;}/* (non-Javadoc) * @see java.lang.Object#toString() */@Overridepublic String toString(){return"Node [data=&quo…
