Finding level of a node on general trees

[indiocolifa]

I'm trying to find the level of a node (which is the root of a subtree itself) in a general tree structure.

The structure definition is (JAVA):

public class ArbolGeneral {
    
    private Object          key = null;
    private ArbolGeneral    hijoIzq = null;    // leftmost child
    private ArbolGeneral    hnoDer = null;    // link to the right node

...

I've successfully found a method to find the height of the tree. This is my implementation:

 public int height(){
        int hmax = 0;
        if (!isLeaf()) {
            ArbolGeneral T = getLeftMostChild();
            while (T != null) {
                hmax = Math.max(T.height(), hmax);
                T = T.getRightNode();
            }
        
        } 
       return hmax+1;
    }

But I cannot find a method to, given a tree T, return the level (depth) of the node (subtree-root) ST as:

T.level(ST)

My bad attempt is here:

  public int level(ArbolGeneral T){
        int h = 0;
        if (this.equals(T))
            return h;
        if (!isLeaf()){            
            ArboGeneral LT = getLeftmostChild();
            while (LT != null) {
                h = LT.level(T);
                LT = LT.getRightNode();
            }          
            return h-1;
        }
        return h + 1;
    }

Any ideas? (Note that I don't want the complete result of course... just a point to a good implementation of method)

THANK YOU VERY MUCH
