Answer 2

What's the point of using a binary tree if you want to use an array? I'm not sure I understand what you're asking. If you want to create a binary search tree, this is what you do:

class TreeNode
{
Object element;
TreeNode left;
TreenNode right;

public TreeNode(Object o)
{
element = o;
}

Here is a good sample program: http://www.cs.armstrong.edu/liang/intro5e/evennumberedexercise/Exercise17_6.java
