New page

Can I just get a simple dang tree class goin up in here plz?

KTNX

Here's a functional tree node:

<pre>
/** Expression Tree Node.
*
* Could make this an <E>,
* or distinguish internal/external,
* operator and number nodes,
* but will make these all expressions.
*
* Could make this process Strings,
* but will assume everything is single-digit,
* single chars only.
*/
class TreeNode {
Character element;
TreeNode left, right;
public TreeNode(Character e) {
this.element = e;
}
public int nChildren() {
int nc = 0;
if(left!=null) nc++;
if(right!=null) nc++;
return nc;
}
public String toString() { /* ? */ }
public Character getElement() { return this.element; }
public void setElement(Character v) { this.element = v; }
public void setLeft(TreeNode newl) { this.left = newl; }
public void setRight(TreeNode newr) { this.right = newr; }
}

</pre>

Put this inside a Tree class:

<pre>
public class Tree {
TreeNode root;

public ExpressionTree() {
root = null;
}

}
</pre>

Git you a nice tree there.
