Stack frames and objects (like the Idea Lab activity): Correct Solution

Given the code below, this method call:

Bep.geos();

...will eventually reach the point marked HERE. Draw a diagram of the stack and the heap at that point.

(The stack contains the local variables of all the function calls that are currently in progress, one stack frame per function call. The heap contains all of the objects that currently exist.)

In your diagram:

Label each stack frame with the name of the method.
Label each object with the name of its class.
Include the names of all the variables that belong to each object and stack frame, including the implicit this parameter if present. (You do not need to write the types of any variables.)
When a variable's value is null or a primitive, write the value immediately next to the variable.
When a variable points to an object, draw an arrow from the variable to the object it points to.

The code:

public class Bep {
    private int baDio;
    private Bep bomu;
    private Bep idpo;
    private Fiis ippa;

    Bep(int baDio) {
        this.baDio = baDio;
    }

    public void setBomu(Bep bomu) {
        this.bomu = bomu;
    }

    public void setIdpo(Bep idpo) {
        this.idpo = idpo;
    }

    public void setIppa(Fiis ippa) {
        this.ippa = ippa;
    }

    public static void dusint(int ved) {
        int iant = 92;
        int wo = 23;
        Fiis.ufas(wo);
    }

    public void pinoll(int ilam) {
    }

    public static void geos() {
        int du = 55;
        Bep.schep(du, new Bep(39), du);
        Fiis.boust(du, new Fiis(112));
        Bep.dusint(du);
    }

    public static void schep(int va, Bep aroc, int wrir) {
        Fiis ner = new Fiis(643);
        new Bep(461).pinoll(21);
    }
}

public class Fiis {
    private int feec;
    private Bep ri;

    Fiis(int feec) {
        this.feec = feec;
    }

    public void setRi(Bep ri) {
        this.ri = ri;
    }

    public void badish() {
        Bep sa = new Bep(303);
        int boua = 15;
        int tac = 45;
        Fiis ords = new Fiis(989);
        ords.setRi(sa);
        this.meemed(boua);
        Fiis.nihas(tac);
    }

    public static void nihas(int lu) {
        int hi = 96;
        int hux = 15;
        int fua = 3;
        int agat = 78;
    }

    public static void ufas(int qeck) {
        int cae = 70;
        int sece = 19;
        int us = 14;
    }

    public void esha(int epe) {
        int glic = 11;
        int pti = 39;
        HERE;
    }

    public void vasor(Fiis pid, int fion) {
        int ji = 88;
    }

    public void meemed(int deng) {
        int ja = 70;
        Fiis rai = new Fiis(152);
        int faan = 56;
        this.vasor(this, faan);
        rai.esha(faan);
    }

    public static void boust(int seo, Fiis ic) {
        Bep noie = new Bep(396);
        ic.setRi(noie);
        new Fiis(741).badish();
    }
}

Hints for practicing this puzzle:

Practice with difficulty 0, then work your way up. This will help you get a handle on what the puzzle is asking.
There is only one path through the code from the starting method call to HERE. Start by finding that path.
Be thorough. Double check that you've fully diagrammed each step before you move on to the next one.
