I am having some problems printing an inOrder traversal of my binary tree. Even after inserting many items into the tree it's only printing 3 items.
public class BinaryTree {
private TreeNode root;
private int size;
public BinaryTree(){
this.size = 0;
}
public boolean insert(TreeNode node){
if( root == null)
root = node;
else{
TreeNode parent = null;
TreeNode current = root;
while( current != null){
if( node.getData().getValue().compareTo(current.getData().getValue()) <0){
parent = current;
current = current.getLeft();
}
else if( node.getData().getValue().compareTo(current.getData().getValue()) >0){
parent = current;
current = current.getRight();
}
else
return false;
if(node.getData().getValue().compareTo(parent.getData().getValue()) < 0)
parent.setLeft(node);
else
parent.setRight(node);
}
}
size++;
return true;
}
/**
*
*/
public void inOrder(){
inOrder(root);
}
private void inOrder(TreeNode root){
if( root.getLeft() !=null)
this.inOrder(root.getLeft());
System.out.println(root.getData().getValue());
if( root.getRight() != null)
this.inOrder(root.getRight());
}
}
