Driver Program to Test Tree in JAVA

Driver Program to Test Tree:-

A basic driver program to test all the functions that i will posting in my blogs using this sample tree.







package com.BST;

public class BSTOperation {

 /**
  * @param args
  */
 public static void main(String[] args) {
  
  BinarySearchTree btree=new BinarySearchTree();
  btree.inorder(btree.root);
  Node node1=new Node(8);
  Node node2=new Node(3);
  Node node3=new Node(1);
  Node node4=new Node(6);
  Node node5=new Node(4);
  Node node6=new Node(7);
  Node node7=new Node(10);
  Node node8=new Node(14);
  Node node9=new Node(13);
  
  btree.root=btree.insert(node1, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node2, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node3, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node4, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node5, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node6, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node7, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node8, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node9, btree.root);
  System.out.println("Inorder");
  btree.inorder(btree.root);
  System.out.println("");
  System.out.println("post order");
  btree.postOrder(btree.root);
  System.out.println("");
  System.out.println("pre order");
  btree.preOrder(btree.root);
 }

Tree Traversal in JAVA (InOder/preOrder/postOrder)

Tree Traversal in JAVA (InOder/preOrder/postOrder):-

Tree traversal can be done through three ways.

1)Inorder:-

Go recursively to the left node.
Read a node
Go recursively to the right node.

2)Pre Order.

Read a node
Go recursively to the left node.
Go recursively to the right node.


2)Post Order.


Go recursively to the left node.
Go recursively to the right node.
Read a node



publicvoidinorder(Node root){if(root==null){return;} inorder(root.left); System.out.print(root.data+","); inorder(root.right);}publicvoidpreOrder(Node root){if(root==null){return;} System.out.print(root.data+","); preOrder(root.left); preOrder(root.right);}publicvoidpostOrder(Node root){if(root==null){return;} postOrder(root.left); postOrder(root.right); System.out.print(root.data+",");}
