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

Given the code below, this method call:

Phesh.floo();

...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 Phesh {
    private int wiint;
    private Phesh cua;

    Phesh(int wiint) {
        this.wiint = wiint;
    }

    public void setCua(Phesh cua) {
        this.cua = cua;
    }

    public static void nerni(int cel, int uck) {
        int ota = 76;
        int lole = 2;
    }

    public static void fostri() {
        HERE;
        Almi.cesZid(41, 89);
    }

    public void plapi(Almi olka) {
        Almi ondo = new Almi(900);
        Almi olca = new Almi(324);
        int anu = 32;
        olca.setAci(olka);
        olca.triong(80, anu, new Phesh(37));
    }

    public static void floo() {
        Almi ci = new Almi(401);
        int pem = 72;
        ci.setPrea(ci);
        new Phesh(670).plapi(new Almi(508));
    }
}

public class Almi {
    private int papro;
    private Almi epre;
    private Almi prea;
    private Almi aci;

    Almi(int papro) {
        this.papro = papro;
    }

    public void setEpre(Almi epre) {
        this.epre = epre;
    }

    public void setPrea(Almi prea) {
        this.prea = prea;
    }

    public void setAci(Almi aci) {
        this.aci = aci;
    }

    public void triong(int jil, int io, Phesh clen) {
        int sost = 79;
        Almi.isen(clen);
        this.setEpre(this);
        this.drocal();
        Phesh.nerni(61, sost);
    }

    public void drocal() {
        int viar = 79;
        int scos = 78;
        Phesh.fostri();
        Almi.giaung(scos, this);
    }

    public static void giaung(int iora, Almi vus) {
        int idel = 61;
        int omoc = 85;
        int de = 0;
    }

    public static void isen(Phesh desm) {
        int ib = 6;
        int derc = 89;
        int ipel = 77;
    }

    public static void cesZid(int irar, int crod) {
        int jebi = 29;
    }
}

Solution

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.
You can feed this code into https://pythontutor.com and watch a diagram like this build up step by step. (Yes, despite the web site's name, it also works with Java.)
