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

Given the code below, this method call:

Grase.sasGlioc();

...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 Grase {
    private int whi;
    private Paop ceir;

    Grase(int whi) {
        this.whi = whi;
    }

    public void setCeir(Paop ceir) {
        this.ceir = ceir;
    }

    public void petis(Grase irlu, int ur, int la) {
    }

    public static void sasGlioc() {
        Paop fo = new Paop(660);
        Grase khus = new Grase(55);
        fo.setVuss(khus);
        Paop.naha();
    }

    public void pnec(Grase aen, int ilhe, int doso) {
        int ekau = 33;
        new Paop(610).smia(doso, ilhe, this);
        this.petis(aen, doso, ilhe);
    }

    public static void snersi(int ishe, int ziss) {
        Paop se = new Paop(505);
    }
}

public class Paop {
    private int naTueth;
    private Paop swi;
    private Grase domu;
    private Grase vuss;

    Paop(int naTueth) {
        this.naTueth = naTueth;
    }

    public void setSwi(Paop swi) {
        this.swi = swi;
    }

    public void setDomu(Grase domu) {
        this.domu = domu;
    }

    public void setVuss(Grase vuss) {
        this.vuss = vuss;
    }

    public void smia(int ewac, int plic, Grase el) {
        Grase.snersi(ewac, plic);
        el.setCeir(this);
        new Paop(602).nokek(28, plic);
    }

    public static void naha() {
        int ui = 27;
        Paop.dios(new Grase(806), ui);
        new Grase(296).pnec(new Grase(2), ui, ui);
    }

    public static void raiSogmed() {
        int trer = 90;
        int aed = 63;
        int orho = 80;
    }

    public void nokek(int sa, int qi) {
        Paop.raiSogmed();
        this.setSwi(this);
        HERE;
    }

    public static void dios(Grase ceim, int som) {
    }
}

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.)
