Convert this to non-recursive

Code Java:

public static int f(int a, int b)
    {
        Z.h1(a, b);           //// arbitrary code
 
        if (Z.h2(a, b))
            return Z.h3(a, b);
 
        else
        {
            Z.h4(a, b);        ////arbitrary code
            return f(Z.h5(a, b), Z.h6(a, b));      //// recursive call
        }
    }

-h1 and h4 --------------------> void functions
-h2 ------------------------------> boolean function
-h3, h5 and h6 -------------->return int
-h1 ... h6-----------------------> will not call f

My Attempt to convert the code above to non-recursive:

Code Java:

 
public static int f(int a, int b)
{
    while(true)
    {
        Z.h1(a, b); //// arbitrary code
 
        if (Z.h2(a, b)) //// base case
        return Z.h3(a, b);
        else
        {
            Z.h4(a, b); /////arbitrary code
 
            int temp = Z.h5(a, b);
            b = Z.h6(a, b));
            a=temp;
         }
    }
}

I'm not sure if I'm right.
Any ideas?
